Study On Ecology Benefit Of Land Arrangements Based On The Ecosystem Services Value Analysis

Land is the material base of existence and development for the mankind, and cultivated land is the most important part of land resources. It is not only related to national food security and social stability, but also to social and economic development and the construction of socialist harmonious society. With the development of economy and increasing population, cultivated land areas are decreasing year by year, and keeping the level of 1.8 billion mu of cultivated land is the precondition of social and economic development. Land consolidation is an important means to increase the amount of cultivated land and keep sustainable use of land resources.Ecological benefits is an important aspect in comprehensive benefits of land consolidation. At present, there is more qualitative research in ecological benefits of land consolidation.According to the research of the theory of ecological benefits of land consolidation and the theory of ecosystem services, there is an new approach to research ecological benefits of land consolidation by quantitative analysis. Based on ecosystem service value, it measures the change of ecosystem service value after land consolidation in order to measure the ecological benefits of land consolidation, which extends the ideas in this field of research.The land consolidation project in Yanli Town of Nanhe County in Hebei Province is taken as an example in this article, and it gives a detailed analysis of the ecological benefits after land consolidation. The results show that ecological benefits of land consolidation is 3.245×107yuan in the project region. Carbon fixation and oxygen production, air purification, climate regulation, water conservation, disturbance regulation, cultural services value increased to varying degrees, and greenhouse gas emissions lose the value of efficiency. We can see the land consolidation has played a certain environment improvement of the project area.
