With construction and development of opencast coal mine, its damage to the land resources and ecological environment in mine area become increasingly serious. Thus, assessing change law of reclaimed mine soils is essential for land reclamation and ecological restoration in ecological fragile area. Is this study, soil Bulk Density, Organic matter, Available P, Available K, Alkali-hydrolyzed N, Total N, pH value, Electrical Conductivity was analyzed in different sampling sites with different reclamation age and an unmined site as a reference in Inner Mongolia mining waste dump. The soil Organic matter, Available P, Available K, Alkali-hydrolyzed N and Total N increased with reclamation age, all the soil factors gradually arrived at their content in original landform. A model of RMSs characteristics was constructed using index sum method. RMSs characteristics had been improved in study area, and gradually arrived at the original landform level. © (2013) Trans Tech Publications, Switzerland.

Land consolidation and rehabilitation is the important measure to achieve quantity dynamic balance and quality increase of farmland, and ecological environment improvement. At present, potential measure of farmland consolidation and rehabilitation in county area is the foundation of land consolidation and rehabilitation plan. On the basis of land change survey in 2010 of Huairou county of Beijing and farmland zones, the previous land consolidation and rehabilitation project results were used and combined with typical survey to calculate quantity potential. Meanwhile, the quality potential of farmland was calculated based on the results of farmland quality classification. Taking administrative villages as units, potential of county farmland consolidation and rehabilitation was analyzed and evaluated, and the research results can provide technical support for making land consolidation and rehabilitation plan in Huairou county. © 2013.

Land rearrangement zoning is to create its direction and key aspect, operate different administration and make land rearrangement measures that in keeping with the real conditions of local area. Huairou district of Beijing was taken for instances, taking administrative villages as zoning unites to get 4 indexes and 10 factors for analyzing based on natural and socio - economic conditions by using comprehensive index value method. Huairou district was divided into 5 areas: plain-agricultural area, hilly-agricultural area, urban-developing area, ecological-protecting area, tourist-developing area after comprehensive analyzing. Direction and key aspects of land rearrangement in each zone were confirmed. This zoning can provide land rearrangement measures targeted in each zone1. © 2013. The authors.

Technical standard system construction has same importance and effect compared with legal system establishment for the development of land reclamation. Land reclamation standard system connotation was initially summarized in this paper according to specific characteristics of land reclamation and standard system, and the basic principle for constructing land reclamation standard system was proposed. Based on the current situation of technical standard system on land reclamation in China, preliminary framework of Chinese technical standard system on land reclamation was put forward according to inner link of land reclamation standard system and land reclamation specialized sequence (including investigation, appraisal, plan, design, budget, construction, monitor and management), and land reclamation standard system that including 27 standards was constructed. The constructed standard system framework contained three levels including primary standard, general standard and special-purpose standard, and it may provide the technical support for the land administration department to strengthen the land reclamation management.

This study aimed to investigate the reclamation pattern for mining subsidence area in loess hilly and gully regions according to land damage degree to achieve the goal of ecological restoration, which is of a significance in management and protection of cultivated land. Based on the MSAS software environment, combining with the mining design and observed parameter, we forecasted subsidence damage of first mining area in slope coal mine. The total area affected by mining was up to 16.54 km2, which dominated by grassland and cultivated land. In these damaged cultivated areas, there were 3.70 km2 of wild damage, 2.41 km2 of moderate damage and 0.17 km2 of severe damage. Therefore, in terms of the natural landscape pattern in the study area, it was suggested to take the fissure filling and the land leveling reclamation measures in the mild damaged arable land. Additionally, slop will be changed into terrace in accordance with the principle of contiguous focus on damaged cultivated land of 4.63 km2 in total. This reclaimed project would increase cultivated land area by 0.40 km2 and decrease the soil and water loss by 49000 t/a. It is concluded that the reclamation pattern proposed in the study is an effective and significant way for restoring cultivated land and controlling soil and water loss in mining subsidence area.
