ABSTRACT
Wu’an is located at longitude 113° 45′∼114° 22′, latitude 36° 28′∼37° 01′. The total area is 1819 km2. It is surrounded by mountains, 30 km away from Handan City, next to Handan City and Yongnian county on the east, Ci County and Fengfeng mining area on the south, She Couny and Zuoquan County on the west, Shahe City on the north. Because of the reduction of the mountains in the central, there is a small plain, called Wu’an basin. Wu’an is rich in mineral resources such as coal, iron, cobalt, aluminum, etc. It is an important energy base in Hebei province, and it is one of the 58 national major coal-producing counties (cities) and one of the four rich iron ore base. Wu’an’s mineral resources are centered on the urban. The iron ore resources are distributed along the south north and the coal resources are distributed along
1 INTRODUCTION
As a special land use patterns, mining can bring tremendous benefits, but may also bring a negligible impact on the ecology and environment of land. The mine ecosystem balance has been heavily destroyed, such as surface mining subsidence caused by underground mineral, cover changing, soil pollution and groundwater destruction (Xu et al., 2012). The qualitative and quantitative study of mining damage to the ecological environment has become an important part of the land ecology. Currently, the methods of mine ecological environment evaluation mainly include index method (Yang, 2004), AHP and fuzzy comprehensive evaluation method (Ma, 2013). All these methods often require different evaluation index and systems for different mining conditions. As a quantitative indicator using in the evaluation of mining disturbance ecology, landscape connectivity can effectively solve this problem.
