Study On The Ecology Security Research Of Cultivated And Reserve Resources Of Cultivated Land Of Balinyouqi In Inner Mongolia Autonomous Region

The ecology security of cultivated and reserve resources of cultivated land is the hit problem now, related to the security of provision and normal running of the national economy. The ecological risk research of cultivated land and reserve resources of cultivated land is imperative. Research methods:Balinyouqi of Inner Mongolia has been selected as study area to research arable resources, supposing reserve resources of cultivated land as cultivated land, regarding arable land resources polygon as small scale ecosystems, utilizing the Analytic Hierarchy Model to choose indexes from considering the exposion of the land, site conditions and soil property and landscape, establishing the evaluation system of cultivated land and reserve resources of cultivated land. Finally using the Entropy method to improve the process to definite the weights through the fuzzy comprehensive evaluation model. We use geostatistics, soil science and theoretical methods of landscape ecology, analysis the ecological safety of cultivated land and reserve resources of cultivated land of Balinyouqi of Inner Mongolia.Research result:the area of cultivated land polygons are 91995.49hm2, the area of reserve resources of cultivated land polygons area275960.00hm2, total area are 367978.21 hm2·Among them, there are 26.59 percent of cultivated land belongs to the high risk status; 55.09% of reserve resources of cultivated land belong to the high risk, total area accounted for 47.97% of all. Research findings:The desertification of Balinyouqi is serious, the ecological risk of cultivated land and reserve resources of cultivated land is in a serious level and needs to be targeted govern. Balinyouqi arable land and arable land reserve resources evaluation process, the right weight greater economic indicators, we can see that, although arable land reserve resources is great pressure on arable land buffer, however, human activities and economic development remains on arable land reserve resources than obviously, the subsequent economic indicators need to be further studied.
