Nations, village communities and individual land users need to make choices about land use in order to support development without risk of land degradation. Computerized land information systems (LIS) based on geographic information systems (GIS) have emerged as powerful tools for generating maps and reports to inform such decisions. Recently, FAO has been developing GIS/LIS systems in linkage with its agroecological zoning (AEZ) and other models, and using them to tackle issues of land, food and people at global, national and subnational levels. They have been successfully developed for land resource management at different scales, but practical difficulties have been encountered in making them accessible to the casual user in most developing countries, due to scarcity of data and poor training support.

This article discusses the issue of land inventory. It is noted that land inventory is one of the main means of ensuring effective land management. In addition, the problems that can be solved by land inventory for the effective management of land resources are demonstrated. It is stated that land inventory is a certain tool for land policy through land monitoring, which allows to identify inconsistencies in land use and land condition. It was revealed that the main purpose of the inventory is to create an information basis for maintaining the state land cadastre, control over land use and registration of land plots. It is considered that the clarification of the legislative regulation of land inventory will contribute to the quality of state management of land resources of Ukraine. The article explored two objects. The current state of use of their lands is analyzed. As a result, ways to solve the problems that exist in the use of land of the State Enterprise «Experimental Farm «Victory» Volyn State Agricultural Research Station of the National Academy of Agrarian Sciences of Ukraine» and the Experimental Station of Tobacco of the National Research Center «Institute of Agriculture of the National Academy of Agrarian Sciences of Ukraine».

Water and land resource utilization is an important driving force of changes in ecosystem services; therefore, research on multi-parameter coupling systems that consider “ecosystem services, water resources, and land resources” together has key significance for river basins. This study aims to reveal the interaction and mutual influence of ecosystem services and water and land resources in the Daguhe River Basin, China, based on the coupling coordination degree model. The results showed that during the period from 2000 to 2010, the coupling coordination degree values for the years 2000, 2005, and 2010 were 0.6005, 0.7292, and 0.8037. The corresponding coupling coordination classifications were categorized as “primary coordinated development”, “intermediate coordinated development,” and “well-coordinated development”, respectively. These results reflected the fact that the relationship between water and land resource utilization and the environment tends to evolve in the direction of coordinated development (an improvement in one part corresponds to an improvement in another part) with variation in water and land utilization types, and eventually pushes the whole resource, as well as ecological and environmental systems, from low to high levels of coupling coordination degrees as observed in case of the Daguhe River Basin, China. Our research provides an overview of the interaction between ecosystem services and water and land resources in the Daguhe Basin and even in the Shandong Province. With our results, we offer new perspectives on river basin management and for planning future eco-environmental policies (the policy is specifically designed for the ecological environment) by combining water and land resource utilization.

Land resources provide stable support for economic development in China. However, due to the scarcity of land, the contradiction between agricultural land protection and construction land expansion is prominent. Under such circumstances, optimal allocation of land resources between agricultural and nonagricultural uses is vitally important. In view of the fact that land resources are indispensable inputs for production activities in agricultural and nonagricultural sectors, reducing the efficiency loss of land resource allocation between agricultural and nonagricultural uses is the only way to optimize the process. Counties are the basic administrative units in China, and their improvement of allocation efficiency will help optimize nationwide land resource allocation. This paper constructs models for estimating county-level land resource allocation efficiency from the perspective of sustainable development and searches for countermeasures to improve allocation efficiency. W County is used as an example to demonstrate how to choose these targeted countermeasures. It is concluded that the best way to optimize county-level land resource allocation between agricultural and nonagricultural uses can be found by estimating allocation efficiency from the perspective of sustainable development.

Guidelines for Surveying Soil and Land Resources promotes the development and implementation of consistent methods and standards for conducting soil and land resource surveys in Australia. These surveys are primarily field operations that aim to identify, describe, map and evaluate the various kinds of soil or land resources in specific areas. The advent of geographic information systems, global positioning systems, airborne gamma radiometric remote sensing, digital terrain analysis, simulation modelling, efficient statistical analysis and internet-based delivery of information has dramatically changed the scene in the past two decades. As successor to the Australian Soil and Land Survey Handbook: Guidelines for Conducting Surveys, this authoritative guide incorporates these new methods and techniques for supporting natural resource management. Soil and land resource surveyors, engineering and environmental consultants, commissioners of surveys and funding agencies will benefit from the practical information provided on how best to use the new technologies that have been developed, as will professionals in the spatial sciences such as geomorphology, ecology and hydrology.

Оценки изменчивости географической среды крупных регионов одно из традиционных направлений Географии. При этом ряд исследователей, экологогеографического направления считают, что в настоящее время изучение нарушенности естественных экосистем (геосистем) одна из базовых проблем Географии. Состояние земельного покрова является одной из наиболее информативных характеристик при оценке изменений географической среды масштабных географических объектов. Относительно легко фиксируемый, лежащий на (земной) поверхности аспект трансформации естественных экосистем/геосистем это изменение структуры земельного покрова и связанной с этим системы землепользования. Практическая реализация данного подхода для мелкомасштабной оценки крупных регионов предполагает использование информации о состоянии земельного покрова, которая отвечает ряду требований. Информация должна быть, в первых однородной по методу получения, во вторых систематически обновляться. В большинстве стран этим требованиям отвечает в максимальной мере информация, которую продуцируют структуры ответственные за ведение Государственного Земельного Кадастра. В России это Росреестр в Канаде Canada Land Inventory, в КНР Ministry of Land and Resources of the Peoples Republic of China и др. Для формирования генерализованного представления о земельном покрове важен метод интеграции земельноресурсной информации, которая может быть получена при использовании данных Государственного земельного Кадастра. При мелкомасштабной характеристике земельных ресурсов береговой зоны Тихоокеанской России использовался метод выделения типов структур земельных ресурсов по административным районам на основании данных Государственного Земельного Кадастра. Monitoring and studying the dynamics of the state of the geographical space is a traditional direction of geographical research, which is carried out at various scale levels. In contemporary conditions, with the intensification of the processes of degradation of natural ecosystems (landscapes), the study of the disturbance of natural ecosystems and dynamics of habitats is becoming increasingly important, especially at the smallscale level. The state of land cover is one of the most informative characteristics in assessing changes in the geographic environment in the course of smallscale geographical assessments. Changes in the structure of land cover and the associated land use system are reflected in the state land inventory statistics. Practical implementation of a smallscale assessment of large regions involves the use of information on the state of land cover, which meets several requirements. Firstly, information should be homogeneous according to the method of its sourcing secondly it should be systematically updated. In most countries, the information produced by the institutions responsible for maintaining the state land inventory meets these requirements. It is Rosreestr in Russia, Canada Land Inventory in Canada, Ministry of Land and Resources in the Peoples Republic of China, and so on. Smallscale assessments of lands means a creation of a generalized image of the land cover of the study area, which can be based on integration of available landresource data from the State Land Inventory. Smallscale characteristics of land resources by administrative districts were used to define various types of land resources patterns in coastal areas of Pacific Russia. Selecting the enlarged types of land resource patterns enables to create an overview map that reflects the general patterns of the spatial differentiation of land cover of the area under study.
