摘　　要： 利用RS和G IS技术分析了湛江市1996—2007年林地数量和其景观格局的变化,定量评价了其对区域生态系统服务功能的影响。结果表明:在12年中,湛江市林地景观总面积显著增加;斑块破碎程度增大,空间格局变得更为复杂;湛江林地景观的格局演变主要受人类活动的干扰影响,林地生态系统服务功能显著增强的结果与其景观空间格局的变化有密切相关性。最后提出了湛江今后的林地保护和发展策略的建议。 Changes of woodtland landscape in Zhangjing City are analyzed and the influences on ecosystem service functions are evaluated by means of RS and GIS techniques.The results show that in 1996-2007 the total area of the woodland increased dramatically and the woodland landscape became geometrically more complex,and ecologically more fragmented.The landscape spatial pattern has been increasingly disturbed by human activities and there was a close correlation between the changes of ecosystem service functions and landscape spatial pattern.Finally,the basic protection strategy and suggestion of woodland in Zhangjiang City were proposed according to the analysis.
