摘要
以防治水土流失和维护景观整体生态优化为目标,选择我国西南喀斯特山地为典型案例,利用遥感资料和地理信息系统(GIS)的空间信息处理技术,采用适宜性评价与景观整体格局优化相结合的方法,探讨了山地景观生态优化的实践途径,在此过程中,山坡地区普遍存在的贫困落后的社会经济状况得到了充分考虑。
The two problems of how to combine the prevention of soil erosion with keeping ecological continuity of the whole landscape, and how to bring the poor and undeveloped social economic state into the ecological planning of mountain areas are emphasized here.Based on this premise, taking the Karst mountain areas of southern western China as the case, and by means of the image processing techniques of geography information system (GIS), a practical approach of ecological optimizing of mountain landscape is submitted and realized.The manner utilized here is mainly composed of three steps, which is respectively evaluating of suitability of representative landscape, functionally dividing of landscape based on the accessibility surface, building corridors and network being made of these corridors, etc.. The remote sensing data of TM image and the contour maps in 1∶50,000 scale are the major data source of the study.
