Tumen River Downstream Areas Of Soil Resources Evaluation

The lower reaches area of ToMen River is situated in the Southeast part of YanBian Autonomous Perfecture, the juncture of China, North Korea and Russia, it is the centre area of the Golden triangle in Northeast Asia. Because of its special Geographical position and good state of reform and open, This area because borderline open city of national level, and is noted by the national and international society gradually. So, using soil rationally, increasing soil fertility to increase the output more have guiding and practical meaning for exploilution of this area.With stint rate style, gradual regression analysis style. Layer analysis style, and according to the imparty of production from different soil, this paper obtain some result by casting, The highest index of dry land is 84. 1 ;The lowest index is 60.O,The highest index of paddy field is 92.O;The lowest index is 43.9, Basis on it, This paper work out the barren chart of the ftirrow soil about the lower reaches area of TuMen River, and offer a improvement measure to some soil and ex-theory to fast development of agriculture economy.
