摘要: 利用1979年、1991年、1999年和2007年4期遥感影像,对广东省鼎湖山自然保护区各功能区内森林景观动态进行对比。结果表明:1)1979—2007年,森林景观优势增加,景观异质性和稳定性下降。2)针叶林、灌丛向常绿阔叶林和混交林转化,导致森林面积增加;针叶林向林间地等非林地类转出,表明针叶林受到较强干扰。3)各同功能区森林变化差异明显,表明缓冲区干扰最强,核心区最低,符合自然保护区功能区划分基本目的。4)保护区西部的森林景观年变化率较高,主要受植被自然演替的影响;东部森林变化率较高,表明缓冲区和过渡区所受到强烈人为干扰。

Abstract: Base on the four period RS images,the forest landscape dynamic changes of different zones of Dinghu Mountain Nature Reserve were analyzed by means of GIS and RS technology. The result showed that 1) From 1979 to 2007,the dominance of the forest landscape was evident,the landscape heterogeneity and stability had a declining tendency; 2) Pine forest and shrublands had transferred into even green broadleaf forest and mixed floret; The Pine forest was transferred into no-forest types and indicated it suffered the strong impact; 3) Core zone had a weak disturbance level,and the buffer zone had the strongest level of disturbance,it conforms to the basic aim of function zone partition of nature reserve; 4) The main driving force of forest change in core zone is the succession of nature,high “AGR” ratio area focuses in the west of core zone; the disturbance was the main force to change the forest in buffer zone and transition area,the high “AGR” ratio area is in the east part.

Key words: Dinghu Mountain Nature Reserve, forest landscape, temporal and spatial dynamic
