| Land exploitation and arrangement project is an important means to solve the contradiction between human and the land and implement the land resource been sustainable utilization. The comprehensive benefit of the land exploitation and arrangement project decide whether the project is successful, it is crucial to supply theory and guide practice to the land exploitation and arrangement project. This article set up a new appraisement system of land exploitation and arrangement project considering the problem which exist in the current appraisement system of land exploitation and arrangement project.The process of set up the new appraisement system of land exploitation and arrangement project as follows:1. Extract the primary component which exist in the economic benefit, social benefit and ecological benefit of the land exploitation and arrangement project by using Primary Component Analysis(PCA) in order to class the appraisement component;2.Screen the main component in the primary component by using stepwise regression analysis, which means reducing the appraisement component not losing the information, and the result is that reduce 28 appraisement components to 13;3.Design the model of land exploitation and arrangement project by using analytic hierarchy process(AHP) with 13 appraisement components.The article calculate the comprehensive benefit of the land exploitation and arrangement project of YONGSHOU country of SHAN'XI province during the feasibility research with the new appraisement system and get both fraction of single benefit and comprehensive benefit. The conclusion as follows:1. The economic benefit of the land exploitation and arrangement project of YONGSHOU country of SHAN'XI province is the most remarkable, and then ecological benefit, which reflect the characteristic of land exploitation and arrangement project in guan Hong plain;2.The component of static payback period in economic benefit has high score, which means the project has fast effect and marked economic; at the time, the value-added of control the soil desertification in economical benefit is also high, which indicated the project embodying the sustainable development in the practice but also in the land utilization;3.The reason people's net income in economic benefit is not remarkable is that be short of water resource to irrigate farm, which influence to increase multiple cropping index and the per unit area grain yield.The actual calculating proved that the land exploitation and arrangement project of YONGSHOU country of SHAN'XI province accord with the local condition, which means the appraisement model is helpful and operable. |
