Terrestrial ecosystem health (TEH) is the basis of regional sustainability development. The state of TEH is an important research direction in the land science field. The purpose of this paper was to explore the development trends and influencing factors of the. By using the radial basis function (RBF), neural network model, geographic information system (GIS), and the comprehensive index method, this paper predicted the land ecological changes of Henan Province from 2007 to 2025 based on a comprehensive evaluation of the system. The results show that the TEH of Henan Province exhibited a general trend of improvement from 2007 to 2025. The predictions exhibited a tendency to fluctuate and increase, from “severe warning” to “moderate warning” and even to “no warning” state. The early warning index of the subsystem showed a fluctuating upward trend except for the press subsystem, which fluctuated between “extraordinary warning” and “heavy warning” states. The overall TEH level is improving but is largely dependent on effective corresponding measures. The health status of the land ecosystem in Henan Province is guaranteed to be stable due to improvements in rural residential incomes, mechanization levels of cultivated land, domestic sewage treatment rates, and the numbers of scientific and technological personnel per unit of land. The TEH is mainly restricted by the population densities, urbanization levels, inputs of fertilizers and pesticides, and average wastewater load factors of the land. To improve the health level of the land ecosystem, it is necessary to reduce the use of fertilizers and pesticides and to control the urbanization rate. At the same time, improving the level of forest coverage and the effective irrigation rate play a positive role in improving ecosystem health. The results provide a reference for land-use planning and management decisions.

AbstractMost of those engaged in town and country planning are aware of the importance of geology regarding their subject. Indeed there are many geologists now engaged in the planning service.There are two areas, in particular, where geological skills will be required on an increasing scale in the future. These are in mineral planning and landfill and restoration on the one hand, and countryside planning on the other.Land use planning is a political process and has as its basis the positive role of development plans and the negative constraints of development control. Development control involves the approval and refusal of planning applications by planning authorities and the Secretary of State for the Environment. Many disciplines contribute technical advice regarding planning but technical advice is just one of the factors influencing any decision since planning authorities are charged with considering all material considerations.

Important Basis

Suitability evaluation is the important basis for scientifically determining the direction of land reclamation. This paper deeply elaborates the goal of land reclamation and the principles of suitability evaluation. land reclamation direction of the project area is initially determines to be cultivated land, forest land, grassland and garden plot based on region land-use planning and analysis of natural factors, socio-economic factors, policy factors of the mining area; the evaluation index system including five involved factors is constructed, and the suitability evaluation of evaluation units is carried out by the comprehensive index method and extreme conditions. Based on above-mentioned evaluation, the land reclamation direction of 14 evaluation units are ultimately determined by comprehensive analysis of the local natural conditions, social conditions and so on.

Greenhouse Gas Inventories

The process of wastewater treatment is one of the sources of greenhouse gas emissions from urban human activities and methane is a source of greenhouse gases can not be ignored. According to the method recommended by IPCC Guidelines for National Greenhouse Gas Inventories 2006,a calculation model was established to assess methane emissions of wastewater treatment in Henan.Then methane emissions from wastewater treatment in Henan province in the year of 2010 were estimated. The results showed that net methane emissions from the sewage treatment process was 21,764.1 tons, and methane from the industrial wastewater generated process was 98,609.33 tons. The results will provide a scientific basis for policy maker to mitigate the methane emission from the sewage treatment process of Henan province.

Urban Risk

With the acceleration of urbanization, the problem of urban risk becomes more and more serious, so it is imperative to build a resilient city. Vulnerability and toughness are interrelated. Vulnerability analysis and evaluation is the way to realize the resilience city. Taking Henan province as an example, this study from the resource, ecological environment, economy, social four aspects to build the urban vulnerability evaluation index system, using the comprehensive index method of the vulnerability of various municipalities nearly 10 years of Henan province to measure and study the dynamic evolution process, so as to provide theoretical reference for toughness of city construction and the practice application.
