基于LUCC的生态环境人为干扰度分析——以广西巴马瑶族自治县为例

Analysis of Human Disturbance to Ecological Environment Based on LUCC: Taking Bama County of Guangxi as An Example

人类活动对生态环境的干扰所造成的影响正日益加强。利用2005年和2017年这2期LUCC数据,用人为干扰度指数与GIS空间分析方法相结合,定量分析巴马县的人为干扰程度及干扰强度动态变化状况。结果表明:(1)这12年来,人类活动对巴马县的干扰程度逐年增加,巴马县人为干扰程度为中度干扰类型;(2)中心城区的人为干扰程度比较高,巴马县内呈现由中心城区向四周逐渐弱化的空间分布特征。从整体来看,巴马县在今后的发展中,更要注意合理利用土地资源,注重保护生态环境,保证该区域的可持续发展。

The disturbance impacts of human activities on the ecological environment have been getting more and more intensive day by day.According to the Land Use/Cover Change(LUCC)data of the years 2005 and 2017,by using hemeroby theory and GIS spatial analysis method,this paper quantitatively analyzed the dynamic change status of human disturbance degree and intensity in Bama county.The results showed that:(1)In the past 12 years,the degree of human disturbance to the ecological environment of Bama county increased year by year,and had reached a moderate degree;(2)The degree of human disturbance in central urban area was relatively high,and it weakened gradually from the center to the suburb of Bama county.As a whole,in the future development of Bama county,it is necessary to reasonably use land resources and to protect the ecological environment for the sustainable development of this region.
