| 摘 要： | 在GIS支持下,结合景观格局分析软件patchanalyst2 0对广州市范围内的耕地资源多样性和破碎度进行定量分析,结果表明广州市耕地资源的空间分布格局主要受到地貌类型的控制,同时受到城市化进程及人为改造利用的干扰,北部山地丘陵区耕地资源的多样性与破碎度较高。保持耕地斑块的多样性及相对完整性对区域耕地资源保护与多元化合理利用具有重要意义。图3,参6。

| Abstract: | Based on GIS with landscape pattern analyst software (Patch Analyst 2.0),diversity and fragmentation of cultivated land in Guangzhou city were analysis in this paper.Spatial distribution pattern on cultivated land resources was main controlled by landform types,and was disturbed by urbanization processes and man-made factors in a certain extent.Results indicated that the grade of diversity and fragmentation were high in hill area in north of Guangzhou city.It is very important to protect the diversity and integrality of cultivated land for land resources development and use rationally. |
