Land Remediation Comprehensive Benefit Evaluation In Hubei Province Nanzhang

Since ancient times, the land resources to support the survival and progress of human society, there is no land, there is no present and future of mankind, is the most important strategic resources needed for social and economic development. But thirty years of reform and opening up, accelerate the process of China’s modernization and growth, industrialization, new urbanization, the total population of geometric growth, and improve the quality of people’s lives, making the tension between land and humans become more severe, contradictions, problems continued. Strategic resource status of land severely shaken, severely hindered the rise of the Chinese nation. Therefore, land remediation measures as an important starting point and the CPC Central Committee attaches great importance to the State Council, which can effectively improve the quality of arable land, increase the number of contradiction relations coordinator.Land remediation benefit evaluation is implementation effect of land remediation testing and acceptance, good and bad effects of the project will directly affect the harmony of society, damage the public interest. Effectiveness studies to carry out remediation of land, can increase the level of scientific decision-making and project management of fine promote rural development project between the benefits generated, avoid loss. Provide theoretical and practical basis for the realization of land remediation projects to optimize the overall efficiency goals. Therefore, land remediation projects that benefit as a benefit evaluation system for scientific research, land remediation to enrich our theory to guide land management practices, to solve the "three rural issues", building a socialist harmonious society is necessary.Articles from the realistic background and pervasive sense to proceed, in terms of land management elaborated on the basis of domestic and elegant theory to explain the nature of the land and its benefits evaluation of governance, guidelines, objectives and rationale for land remediation benefit evaluation method to analyze comparative study combined with feature selection evaluation of the project itself, the combined effect of the establishment of land remediation evaluation factor system, building land remediation comprehensive Benefit Evaluation mathematical models. By the first of AHP and Entropy Law is indeed the right weight correction, using fuzzy math economic evaluation method and physical element method for land remediation activities, ecological, social, landscape benefits and comprehensive benefits for quantitative evaluation and qualitative assessment, so as to achieve its objective optimization.Land remediation applications benefit assessment methods, systems and models, Hubei Xiangyang Nanzhang nine town land remediation project as a case of combining theoretical and practical analysis, the results show that:through the implementation of land remediation projects, each of which produces efficiency has improved so much in line with the wishes of the original project when the project decision makers. Effectiveness evaluation model in two articles on the system itself benefit analysis, research, combines the advantages and disadvantages of the two evaluation methods to maximize the extent of excluding subjective factors influence the evaluation, so that the result is more realistic for the future land remediation activities establish a benchmark of conduct, but also to copy all of the methods described herein to other similar projects in order to pursue the project to optimize and maximize efficiency. During the course of the study, I found that the land remediation project issues and outcomes exist, its social, ecological and landscape needs to be greatly improved efficiency and breakthrough, the next round of land remediation project will also focus on this.
