Taking Guangxi agriculture and cultivation state-owned Jinguang Farm, Qianjiang Farm, Xinxing Farm and Liangqi Farm as land reclamation cases studies, 16 evaluation indices were selected from four aspects, i.e., investment in land reclamation project, implementation intensity of land reclamation, land use structure, and efficiency output of land reclamation, to evaluate the reasonability of land reclamation in the project area. The improved TOPSIS method and obstacle degree model were used to evaluate reasonability and diagnose obstacle factors. Results showed that the efficiency output of land reclamation had the greatest impact on its reasonability, followed by land use structure, with investment of land reclamation project having the least impact. The index obstacle factors mainly referred to the improved value of land quality. Through analysis of the evaluation results, the reasonability and obstacle factors of land reclamation were objectively determined to provide a reference for land reclamation in practice.

The Cost

In this work, an economic assessment of environmental damage to water and land resources is calculated, and the cost of a project for the reclamation of destroyed lands within the territory of the Komsomolsk gold recovery plant is determined. The object of the study is directly the territory of the enterprise, which is located in the Tisulsky municipal district of the Kemerovo region. According to our calculations, the total assessment of environmental damage from the plant’s activities amounted to 458 million rubles, of which: 294 million rubles – accumulated environmental damage from water pollution; 164 million rubles – accumulated environmental damage from soil pollution in the surrounding area. The cost estimate of the destroyed land reclamation project amounted to 716.7 million rubles. At the same time, income from the sale of equipment and gold mined in the territory of the tailing dump reaches 3916 million rubles.

AbstractIntegrated renovation projects are important for marine ecological environment protection. Three-dimensional hydrodynamics and water quality models are developed for the Maowei Sea to assess the hydrodynamic environment base on the MIKE3 software with high resolution meshes. The results showed that the flow velocity changed minimally after the project, decreasing by approximately 0.12 m/s in the east of the Maowei Sea area and increasing by approximately 0.01 m/s in the northeast of the Shajing Port. The decrease in tidal prism (~ 2.66 × 106 m3) was attributed to land reclamation, and accounted for just 0.86% of the pre-project level. The water exchange half-life increased by approximately 1 day, implying a slightly reduced water exchange capacity. Siltation occurred mainly in the reclamation and dredging areas, amounting to back-silting of approximately 2 cm/year. Reclamation project is the main factor causing the decrease of tidal volume and weakening the hydrodynamics in Maowei Sea. Adaptive management is necessary for such a comprehensive regulation project. According to the result, we suggest that reclamation works should strictly prohibit and dredging schemes should optimize in the subsequent regulation works.

Impact Of Mining

The purpose of the study is to influence land resources during mining operations, and the main stages of land reclamation during mining on the example of the Tyradinsky gold Deposit, the "Zolotaya Tyrada" quarry, located in the Yenisei region of the Krasnoyarsk territory. The main factors of impact on land resources in the process of mining the field are considered; the analysis of measures to reduce the negative impact on land resources in the process of mining the field is carried out. The actual height and area of overburden dump not to exceed project, the reconfiguration of dumps allowed us to reduce the impact of mining on the environment, to avoid placing parts of the dumps in the water protection zone of the river Terada, thus there is no need of land allocation to forests of the first group and reduced the amount of removed topsoil. During the reclamation, potentially fertile soils (loam) taken from the quarry were used. There will be no deterioration in the impact on land resources during the liquidation process, due to the short duration of the work and within the existing land allotment.

Integral Assessment

Relevance. The effective use of agricultural land is a fundamental prerequisite for the successful implementation in the agro-industrial complex of the task of providing the population with food, and production with raw materials. At the same time, the issues of methodological support of the procedures for determining the integral indicator for assessing the use of agricultural land, established on the basis of a theoretically grounded unified approach based on quantitative methods, have been developed with insufficient completeness. Actualization of the issues of improving the theory and practice of assessing the effectiveness of the use of agricultural land in agricultural production is becoming one of the priority tasks of land reclamation science. The purpose of this work is to create a methodological basis for the process of assessing the use of agricultural land, which guarantees the comparability of the considered options for agroproduction in different natural and economic conditions.Methods. The research is based on the method of point assessments for indicators of agricultural land exploitation and the formation on their basis an integral criterion of land use efficiency. The proposed procedure includes: analysis of statistical data characterizing the dynamics of the values of indicators of used land resources, calculation of local assessments of the feasibility of their exploitation and assessment of the efficiency of land use according to a generalizing criterion represented by the sum of these local assessments.Results. A methodology has been developed and a method has been created for determining the efficiency of the use of agricultural land, based on a generalized integral assessment of the operation of agricultural land, which allows to identify bottlenecks in agricultural production and outline rational directions for the development of land use. The testing of the algorithm of the methodology and capabilities of the scale for the integral assessment of the efficiency of the use of land resources was carried out on the example of the Non-Black Earth Zone of the Russian Federation. Shown is an unsatisfactory (below the national average) contribution of agricultural production to the gross regional product. On the whole, positive dynamics of agricultural production in the Non-Black Earth Zone was established, which is achieved due to the development of animal husbandry, which is an effective factor in the formation of modern efficient agriculture of the territory, with the orientation of the crop production system on the raw material basis of feed production or the sector of the economy of the agro-industrial complex of the territory.
