Reserch On Land Use Of Mizhi County In Shannxi Province

In the 21st century, the global change research has promoted the research progress of land use, and has made comprehensively changed people's understanding of the concept and research methods of land use. In our country, as a major national conditions and strength investigation, the national land survey is purpose to find out the national comprehensive land use status, grasps the real land based on data, and informationize the results of investigation, networking management, establish and improve the system of land survey, statistics and registration, realize the socialization of land resources information services to meet the development of economy, society, land macro-control and land resources administrative needs.MiZhi county land survey of the second national rural land survey, total check the county total land area of 117869.84 hectares. All countries (G) land area of 1477.30 hectares, accounting for 1.25% of the total land area; (J) collective all land area of 116392.54 hectares, accounted for 98.75%. Among them: the cultivated land area of 46509.89 hectares, accounting for 39.46% of the total land area; Garden land area of 14440.03 hectares, accounted for 12.25%; Forest land area of 12844.05 hectares, accounted for 10.9%; Grassland area of 33379.73 hectares, accounted for 28.32%; Town village and industrial and mining land area of 3538.99 hectares, accounted for 3.0%; Transportation land area of 1274.37 hectares, accounted for 1.08%; Water and water conservancy facilities area of 998.23 hectares, accounted for 0.85%; Other land area of 4884.55 hectares, accounted for 4.14%.Through the research of quality, precision analysis and evaluation, the use of MiZhi county land use historical data and current situation of comparing data, this paper discusses the related land use change caused by the leading factor, and the reasons for such changes are analyzed and summarized, combined with the practical situation, rational utilization of land resources related countermeasures. The main conclusions of the study are as follows:(1)The forestry land, the bushes for further reform, increase the coverage or directly to the afforestation, land development, new woodlands and condition of low forest land reform at the same time, make forestry land economic and ecological benefits can be improved. reuse of a light situation, through the cropland conversion forest area increased. (2)Current MiZhi county garden area ratio still partial small, can use farmland, forest land and grassland and other land to develop trade. At the same time in the garden should strengthen existing economic forest tree species in the transformation of the fruit tree species of change.(3)Cultivated land internal appropriate proportion of food crops to compression, increase the proportion of economic crops. To develop trade and's whole spinach industry, not only can promote the improvement of land utilization, also can promote the development of commodity economy. To achieve this result, they must work to improve the agricultural intensive management level. Through the scientific method farming, not only to land, also want to pay attention to the cultivated land protection, according to the balance of the ecosystem theory, puts forward improving soil fertility, maintain sustainable production measures.(4)Grass increase other grass of reform of the development efforts, to increase artificial grassland area, improved update natural grassland.(5)To strictly control the towns and villages construction land. The rapid population growth.(6)Eestablish ecological agriculture basic farmland system, improve the land utilization rate...
