Extensive Decision-making Study About Comprehensive Administration On Slope And Cultivated Land In The North District Of Shan-xi Province

On the ground of cultivated-land system in north region of Shan'xi, and using corresponding analysis method of extensive dision-making theory(containing, dispersing, correlation and conjugation), The dissertation, after making a thorough investigation of corresponding region(such as geographic distribution, climate hydrology, soil type and slope rankand and so on), qualitative and quota, analyze four major contradiction in cultivated-land system(ecology contradiction, economical contradiction, social contradiction and the technology contradiction)and related reasons. In addition, the article uses E-object equation to establish math model about how to take agriculture land from the forest or grass of north region in shan'xi, finally, the article gives a real diagnosis research on the basis of cultivated-land system in Yu-lin and gets some Land resource disposition plan, besides, supplies result analysis and way of realization.There are two innovation places: first, on the progress of tactic studying, the article Introduces widely applied governmental model: Silt dike construction and small basin comprehensive program besides traditional method of land to forest and land to terraced field. And both have its own applicable scope. Second, the article introduces for the first time E-object equation to carry on mathematics modeling. This method makes an effective union of goal-plan and extensive theory which could overcome disadvantage of traditional aim-programming (unable to make some variation of Parameter), more objectively, the model reflect what is in cultivatived land.The paper's conclusion produces the slope farming government strategy collection, and this strategy collection is a formed opinion after having considered comprehensively in government technology, economical development, policy laws and regulations, ecology influence. Aiming to supply a decision method trying to conform to the ecology construction condition requirement as well as achieve the maximal benefit, the article tries to enhance the agricultural income, improves fanner's life condition in west region, thus enhances farmer's overall income, and provides policy-making scientific basis for the government department.
