Multilayer fuzzy synthetic evaluation is an effective method of the qualitative analysis into the quantitative analysis, and can reflect the different levels of objective things factors, avoiding the difficult to assign weights due to excessive factors. Geological environment of Jiawang coal mining subsidence area in Xuzhou was evaluated with an indices system based on multilayer fuzzy synthetic evaluation. Through evaluation, the serious damage region of geological mining of Jiawang mining subsidence area is 1918.966 hm2, and the more serious damage region is 2524.088 hm2, and the less affected area is 1366.971 hm2. The results showed that the geological environment of Jiawang mining subsidence damage is more serious. The farmland was destroyed seriously, and water due to land collapse was quite serious, which was difficult to land reclamation. It is believed that this work may provide scientific reference for land reclamation and landscape ecological restoration of coal mining subsidence area.

Both coal mine and land are important natural resources that human depend on for existence and development. Coal mining has contributed greatly to the development of economy and society in China. Meanwhile, subsidence induced by coal mining has seriously affected human life, ecological environment and development of regional economy in mining area. Thus, aiming at coal mining subsidence area, this paper puts forward two kinds of land reclamation techniques containing engineering reclamation technology and biological reclamation technology, which can scientifically guide land reclamation practice, coordinate relationship between human and land and relax ecological crisis.

The artical is based on the investigation of the basis of the status quo of Zhuxianzhuang and Luling coal mining subsidence area in Anhui province Suzhou city(hereinafter referred to as the "Zhu Lu subsidence area"), a preliminary analysis of the dynamic change trend of detention space in Zhu Lu subsidence area, and based on the hysteresis storage conditions of subsidence area, use the flood routing model to simulate the hysteresis effect of storage at different subsidence scenarios of different frequency flood. Finally, using the experience type channel evolution model and peak delay routing model further revealed storage effect on flood process of Zhu Lu subsidence area.
