The Research Of Development And Protection About Land Resources In The Western Region Of Jilin Province

Land resources is the necessary conditions for human survival and development,production and all activities of human life can not be separated from land,Land resources is natural product,and they are non-renewable resources,so people often make use of land by changing the barren hills,wasteland,river, beaches, marshes, such as the shape of the existing land,physical and chemical properties and use,to achieve the development of socio-economic about demand for land resources. In the process of the use about land resources,to pursuit of short-term economic benefits resulting from reduction of arable land, land quality, destruction of ecological environment and other issues have been threaten all aspects of the socio-economic development. The western region of Jilin Province is located in at the western end of Songnen Plain, is a fragile ecological environment in north China with the eastern starting point. To implement of the"tens of billions of kg of commodity grain production in Jilin Province capacity-building master plan"in such a fragile ecological environment about the western region of Jilin Province, how to make rational use of land resources of great significance.Ecological environment of the western region of Jilin Province mainly for the poor stability, high frequency of natural disasters, natural factor of poor coordination between. The proportion of agricultural land has been maintained at around 77.5% in the utilization of land resources. And proportion of arable land in 2000 increased by 54.23% to 54.37% in 2006; although the proportion of grassland no change in the proportion, but the absolute value is decrease; the proportion of forest land increased by 17.55% to 17.97%; surface of the water by the year 2000 dropped to 6.42% percent in 2006 5.84%, reduce 28,669.18 hectares. The proportion of building land is decline in 2000 from 8.25% to 6.89% in 2006. Which the proportion of land about residents and industrial sites, water conservancy facilities is shown clear signs of an upward trend, respectively in 67.41% and 13.49% by 2000 to increase in 2006 of 14.70% and 80.96%. But traffic sits shown clear signs of a downward trend, dropped from 19.09% in 2000 to 4.35% in 2006. Over the years, because of the growing strength about human activities, such as overgrazing, grass cultivated fields, urban construction, as well as a number of water conservancy projects, the negative effects of severe land degradation, desertification, salinization, grassland and wetland degradation is widespread atrophy. Wetland resources, grassland resources in the western region of Jilin Province is an important ecological resources, with the ecological functions about the maintenance of biological diversity, maintain the regional ecological balance, but the wetland resources and the number of grassland resources has been a downward trend in the utilization of land resources. The change in land use about the western region of Jilin Province, although the current development in the region to see a certain role in promoting, but it is shot. Because in the long time, it is will not only further deterioration of ecological environment in the region, but also for the sustainable development of the regional economy will also have an adverse impact on.In recent years, improve the ecological environment, rational development and utilization and protection of land resources in the western region of Jilin Province has become a regional development strategy. The development and utilization of land resources in such fragile ecological environment of the western region of Jilin Province, in the first place to protect the ecological environment, combined with the overall layout of agricultural development and utilization of land resources, scientific development and the development of land-use planning. First, through the grassland to actively, promote Circle rearing methods to protect grassland resources, to prevent further loss of grassland resources; Second, by strengthening the awareness of wetland protection to prohibit the blind development of wetlands for farmland, the establishment of a comprehensive water conservancy facilities and pay a good mechanism to protect the wetland resources, to prevent further loss of wetland resources; Third, the region in accordance with the characteristics of land resources, the introduction and popularization of fine varieties, and continuously improve the quality of agricultural products, well-planned, well-planned and organized to carry out the adjustment of agricultural structure; Fourth, to strengthen water conservancy facilities and to develop water-saving agriculture; Fifth, policies to improve the system, due to the transfer of population to other regions; Finally, by changing the emphasis on farmers of arable land "with" light "maintain" the idea of the use of technical means to transform low-yielding fields.
