Changes of ecological environment in the Dexing copper mine based on TM images
摘要
Abstract
The changes of the ecological environment of the Dexing copper mineral resources development area in the past two decades were studied in the aspects of ecosystem structure and ecosystem landscape pattern reflected by the remote sensing images obtained in 1992 , 1996 , 2000 , 2004 , 2009 and 2013 . According to the results obtained, the development activity in the Dexing copper mining area led to the continuous decrease of forests, grasslands and other natural landscape areas and the unceasing increase of mining field, tailings, field area dump and other artificial landscape areas; regional ecosystem quality became worsen and worsen, the ecosystem fragmentation was aggravated, and the overall performance was towards the increase of the ecosystem mean patch areas and the patch density, together with the decrease of aggregation index. Over the past two decades, mineral resource extraction activities became increasingly intense, the ecosystem damage area was increased year by year, whereas the ecological restoration project for this area was lagging behind.关键词
