The Study Of Ecological Security Spatial Structure Of Regional Land Consolidation

Land reclamation project is an important way to increase the available arable land area, reduce the pressure on arable land and adjust the agricultural structure. Agricultural development in the modern sense, not only is the process of agricultural production growth, and must pay attention to the effects of agriculture on the ecological environment, is a kind of economic, social and environmental process of common development, study the effects of land consolidation on the ecological security is a necessary condition of regional sustainable development. The ecological footprint method is internationally recognized as an effective method of regional ecological security evaluation, this paper based on the theory of ecological footprint and ecological security, based on principles of social, economic, environmental, common development, According to the actual situation before and after the Quyang county Chande village project implementation, combined with the related data analysis software, discusses land reclamation project the effects on the regional ecological security. In this paper, the conclusion mainly include the following:(1) Based on the ecological carrying capacity, ecological profit and loss, ecological pressure index and ecological footprint of ten thousand yuan GDP on several aspects, such as land reclamation project area before and after the project of ecological security situation, this paper compares and analyzes the ecological footprint method can accurate and effective evaluation of regional ecological security situation, this study for land reclamation project plan formulation and provide theoretical basis for regional ecological security evaluation work.(2) After the land reclamation project implementation in the project of ecological surplus increased by91068.64hm2, indicates that the implementation of the land reclamation project, make the overall ecological security situation improves, to resist the ability of the ecological risk. However, the grassland ecological deficit further, from505.59hm2down to685.27hm2. On the geographical distribution, the grassland ecological deficit is larger, the king of one of the biggest Dachuan village ecological profit and loss is141.92hm2, obvious regional differences, investigate its reason, mainly is Dachuan village in the process of land management, through a large number of grassland agricultural structure adjustment, transformed into farmland, therefore in the process of land reclamation, should pay attention to the reasonable planning of land use structure.(3) The project overall ecological pressure index from2.69to1.97, the ecological security level increased to highly safe from unsafe, ecological environment, still have large pressure on ecological supply and demand contradiction of partial improvement, but still to be further improved. Ecological security index rose a king Zhuangbei village, Lijiazhuang village and Jiabeizhuang village, and the ecological safety of Lijiazhuang village and Jiabeizhuang village deal don’t changed from very unsafe to highly secure, showed that the three village land renovation project of ecological security status deteriorating even further. Ten thousand yuan GDP reflect the regional resources and economy, the relationship between the land before the renovation project implementation, project area ten thousand yuan GDP is0.1538hm2per ten thousand yuan, after the project, an average of ten thousand yuan GDP is0.1176hm2per ten thousand yuan, shows that infrastructure and land use structure adjustment to the unit of land resource and energy efficiency, and then show the demand for the ecological environment pressure reduction.
