Study On The Benefit Calculation Of Comprehensive Renovation Of Land In The Hill Regions Of Sichuan Province

With the accelerated pace of industrialization and urbanization, Bottleneck problem of land resources is more prominent. Land renovation can increase the cultivated land area, improve land use efficiency and relieve contradiction of land. The land profit diffusion conducive to scientific research a reasonable distribution of the benefits, improve the land the management level, so as to provide a theoretical basis for related decision-making.The study summarized in domestic and foreign land renovation and the profit diffusion land research progress, On the basis, The study uses scientific development theory, system theory, cost and benefit theory and the land supply theory, applies a contrastive analysis, income reduction method and alternative approach and ecological service value coefficient method to analyze the source of the benefit land and cost structure, and combined with the practice of Sichuan hilly land, from the economic efficiency and the social efficiency and the ecological efficiency to select the15index, building the land renovation of the measure benefit index system, constructing the land renovation benefit estimation model. To take ShiHe town land renovation project as an empirical research.1. The study analyzed the source and the benefit of land cost structure. This study expounds the land economic benefit and social benefit, ecological and landscape benefits source; A systematic analysis of the land cost structure regulation, including the land unknitting work cost, irrigation and drainage engineering cost, the cost of the project, road farmland protection and shelter forest engineering cost, etc.2. Constructing the land renovation benefit estimation model. This study from the economic efficiency and social efficiency and the ecological efficiency to select the15index, building the land renovation of the measure benefit index system, constructing the land renovation benefit estimation model.3. The empirical research.Using the estimation model to calculate the project benefit, the comprehensive benefits are248.0314million, the economic benefit is110.6394million, the social benefit is137.392million, the ecological benefit is554000yuan, the social benefit is significant. The study shows that the established estimation model is scientific and reliable.It has higher application value; land renovation brings good economic, social and ecological benefits by smaller investment. In the comprehensive benefit of land, the proportion of economic benefit and social benefit is more obvious, but the ecological efficiency is not very obvious, because time is short.4. Countermeasures. Firstly, opening source throttling, reducing the cost of land, and guiding the folk capital into the land area; Secondly, adjusting measures to local conditions, combining hilly area in Sichuan province industrial development in the actual land; Thirdly, According to different situations, encouraging farmers to participation in the collective, giving full play to the role of farmers in the land; Fourth, increasing the ecological environment control investment, improving the land the ecological benefits.
