For connecting with the international market quickly and meeting the challenge and the opportunity given by the entrance of WTO for agriculture, the adjustment of agriculture construction has become the most important event of the agriculture development. The Jilin province is a big agricultural province, and the Qian'guo county is Jilin province's important agricultural county. So it's agricultural construction adjustment is particularly important.Based on the GIS, this paper firstly use 'the technology of drainage basin diversion based on the digital terrace analysis' mark off the little drainage basin of Qian'guo county. Secondly by explaining the remote sensing picture and folded with the picture of little drainage, coverage map, geologic map and the picture of DEM, get the types of the natural land and types of the land-using, then analyse and contrast them, find their fitting relation, combined with the degeneration data, work out the ecological support level for the adjustment of the little drainage. Furthermore choosing agriculture related social and economic factors and according with their relative criterion, elicit their support level. And according by their importance to the agriculture, calculate the support level for the adjustment of agricultural construction of the social and economic system. Forth, using the software of SPSS cluster the support level of ecological system and the social and economic system of the little drainages, and get five types of them: ecological system and social and economic system both supporting, social and economic system supporting but ecological system not, ecological system supporting but social and economic system not, not very supporting and none supporting. Finally based on the classification of the supporting level, deduce five types of agricultural construction adjustment: Holistic superiorityEcological supporting Social and economic supportingSpot superiorityEcological restoration...
