Study of Ecological Restoration and Reconstruction in Sichuan Earthquake Disaster Area —— Taking Mianyang city as an Example Min Zhao1,a, Jian Yang2, b Xiu Li3, c 1,3 Southwest University of Science and Technology School of Civil Engineering and Architecture ,Mianyang ,Sichuan, 621010, China 2 Southwest University of Science and Technology School of Applied Technology, Mianyang ,Sichuan, 621010, China azhaomin@swust.edu.cn, byangjian@swust.edu.cn, clixiu@swust.edu.cn Keywords: ecological restoration, reconstruction, Mianyang, ecosystem Abstract.
The earthquake caused the surface material loose, displacement and alienation, caused farmland area decreases, quality drops, the degree of damage has a directed relation about the lithologic structure and stability of surrounding mountain.
● Adhere to the principles of people-oriented, respect nature, respect for the science.Post disaster reconstruction is a comprehensive engineering, including ecological ,economic, social, industrial, infrastructure, it should fully consider the carrying capacity of resources environment and local economic and cultural characteristics, through the scientific guidance, democratic decision-making, overall planning, step by step, in the process of reconstruction planning and reconstruction , comprehensively implementing the view of ecological civilization and scientific outlook on development.
●Combined with ecological restoration project and management of resource, environment.Ecological restoration and reconstruction is inevitably involved in departments of development and reform, water resources, environmental protection, land resources, forestry, construction, agriculture, transportation, science and technology, tourism, need to carry out inter-departmental cooperation, establish a unified planning and implementation mechanism, it has a solid organization and guarantee that can solve the contradiction including development and protection , the interest conflicts in processing different development goal, need to establish a coordination mechanism and evaluation system.
