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。
Using RS and G IS techniques, we analyzed the changes of forestland quantity and landscape pattern in Zhanjiang City from 1996 to 2007, and evaluated its impact on the service functions of regional ecosystems. The results showed that in 12 years, the total area of forest landscape in Zhanjiang increased significantly; the degree of plaque fragmentation increased and the spatial pattern became more complicated; the landscape evolution of Zhanjiang mainly affected by the disturbance of human activities, and the forestland ecosystem service Significantly enhanced results are closely related to changes in landscape landscape. At last, it puts forward the suggestion of Zhanjiang’s strategy of forest protection and development in the future.
