基于遥感技术的乌海市工矿企业监测和生态承载力分析

Analysis of monitoring of industrial and mining enterprises and ecological carrying capacity in Wuhai City based on Remote Sensing

乌海市是我国西北地区典型的资源型城市,伴随着煤炭资源的逐渐枯竭,乌海市可持续发展受到影响.而生态承载力是衡量可持续发展的重要指标.通过利用中、高分辨率遥感影像,监测乌海市工矿企业和土地利用变化,分析其对生态承载力的影响.结果表明,与2004年相比,2014年乌海市新增加工矿企业41个,增幅达49.4%.由于乌海市人口增加以及新增加的工矿企业占用草地、水体等生态型用地,致使乌海市人均生态承载力由0.309公顷/人下降到0.265公顷/人.

Wuhai is a typical resource-based city,which is located in Northwest China.The sustainable development of Wuhai will be affected by the gradual depletion of coal resources,Ecological carrying capacity is an important indicator of sustainable development.With the medium and high resolution Remote Sensing data,the distribution of industrial and mining enterprises and the variation of land use were monitored,and the influence of the variation of land use on the ecological carrying capacity of Wuhai was also analyzed.The results were as following:comparing with 2004,the amount of industrial and mining enterprises increased 41 in 2014 and the increase rate was 49.4%.Since the increase of the amount of industrial and mining enterprises and their occupation of ecologically land area such as grass and water,the ecological carrying capacity per capita of Wuhai decreased from 0.309 hm^2/person to 0.265 hm^2/person.
