Research On The Ecological Effect Of The Land Use Based On The Sand Ground Of Horqin Which Was Grain For Green

Grain for green is a national ecological project in the central and west regions in China. It has proved that grain for green is a great method of improving the ecological environment . The sand ground of Horqin is the important area for grain for green project. With the implementation in ecological projects , such as grain for green , green speed accelerates obviously. In order to reflect the ecological construction situation truly and make the following work to practice smoothly in this area, using quantized research on the ecological effect of the grain for green construction in this area is necessary, no matter in theory or practice angle.After the analysis through the whole course of implementation of the grain for green project, District Naiman Banner choose has been chosen as a typical target of this research. The methods of this article are qualitative and quantized research combining the field and investigate. Supported by remote sensing , GIS technology, it analyses the recent image and character of grain for green in Naiman Banner using the remote sensing image of Naiman Banner and various kinds of statistical data and data of relevant grain for green . Then it obtained the quantity , quality and the changed imformation in the past five years in the typical district in sand ground of Horqin. Based on this, using mathematical statistics and space pattern analytical method and choosing certain evaluation index and pattern index of the ecological effect, it research the ecological effect after grain for green from three angles which are ecological structure rationality , ecological environmental quality and ecological effect space. Finally, the article analyses the main reason that existing in the course of grain for green in Naiman Banner, then propose some...
