| 摘 要： | 人为水土流失是一种人类干扰下的典型景观退化现象．将人为侵蚀在空间上的表现称之为人为侵蚀景观．在遥感和GIS技术支持下，结合大量的实地调查资料，对珠海最主要的人为侵蚀景观类型——土石场开展空间分布分析和景观生态影响评价．调查范围内珠海土石场有235个，其中三灶、井岸两镇(区)分布最为集中，分别为28、29个．缓冲区分析表明，土石场的分布与距交通道路的远近呈对数线性相关，其中在距交通道路100～200m距离范围内分布最为集中．设计景观生态影响度评价指数，对面积大于5000m^2的152个土石场进行景观生态影响度评价结果表明，对周边景观生态环境影响极强的土石场有9个，属于强一级的有17个，应首先对这些土石场开展景观生态恢复．

| Abstract: | Artificial erosion is one of the typical artificial landscape degradation. Based on the support of GIS and RS and combined with field investigation data, the spatial distribution characteristics and landscape ecological impact degree of quarry were analyzed. There were 235 quarries in Zhuhai city, which concentrated on Sanzao town and Jingan town. According to buffer analysis, the quarries distribution had a obviously logarithm relationship with its distances from roads. 152 quarries with the area of more than 5000 m 2 were assessed by landscape ecological impact degree (LEI) index. The results indicated that 9 quarries belonged to great influence level and 19 quarries belonged to strong influence on ecological environment. |
