- 摘要:
- 土地利用变化的环境效应已成为区域可持续发展研究的切入点与突破口。以石家庄地表水源保护区为例，利用Erdas IMAGINE、ArcGIS等软件对2000年TM和2010年环境一号星的遥感影像进行解译，分析近10 a来保护区土地利用的变化情况；将保护区划分为5个区域，并利用SPSS软件，将分类结果与保护区主要水质污染指标TN、TP、BOD5、CODMn进行相关性分析。研究发现：各土地利用类型的变化情况较大，变化概率为40.83%~67.87%，主要是低矮灌木及草地、未利用地向林地的转变；建设用地与TN相关性显著，其他各土地利用类型与水质指标之间相关程度不高。研究成果不仅对石家庄及河北省山区今后的土地利用和水质保护具有一定的指导意义，还将有助于揭示流域人类活动与景观生态系统变化和水环境的交互作用机制。
- Abstract:
- The environmental effect of land utilization change has become a starting and breakthrough point in the researches on the regional sustainable development. In the light of surface headwaters protection areas of Shijiazhuang, TM of 2000 and the remote image of No. 1 Environmental Satellite of 2010 was interpreted by using Erdas IMAGING and ArcGIS, and the change of land utilization of protection areas in the past decade was analyzed. And the protection areas was classified into five regions and performed a correlation analysis of classified results and TN, TP, BOD5 and CODMN. The results showed that there was a big change in the land utilization types, the change rate ranged from 40.83% to 67.87%, the major change was the conversion of low bushes, grasslands and unutilized land into woodland. The correlation of construction land and TN was obvious, but the correlation of other land utilization types and water quality was not obvious. This study would be of guiding significance to the land utilization and water protection in Shijiazhuang and other areas in Hebei. And it will be helpful for revealing the interactive mechanism of human activities of drainage areas and landscape ecology and water environment.
