Study on the Change of Landscape Ecological Quality Based on Land Use: A Case Study in Resource-Exhausted Mining Area

Abstract:

In order to research the effect of land reclamation on landscape ecological quality(LEQ) in mining area, taking Jiawang mining area in Xuzhou as an example, LEQ and its changes before and after reclamation were evaluated with an indices system which was constructed form stability and interference level of landscape ecosystem based on RS, GIS and landscape ecology. The weight was assigned for each index by analytical hierarchy process (AHP) and entropy technology. The results showed that land use of the study area dramatically changed, manifesting by farmland continuous decreases and the built-up areas rapid increases, secondly, woodland decreases after increasing, grassland and water slight increases, which were in an unbalanced state overall. The landscape ecological situation of the study area had a better trend from 2001 to 2010, implying that land reclamation project had played a certain improvement on the regional ecological environment in mining area. It is believed that this work may provide scientific reference for land reclamation and landscape restoration of coal mining area.
