摘  要：
本文以2003年长沙市森林资源二类清查数据和2003年TM遥感数据为主要信息源,借助3S技术平台,运用景观生态学原理和方法对长沙市边缘区城市森林进行了景观格局梯度分析,结果表明:在斑块类型水平上,城市森林景观类型在样带梯度上表现出明显的"梯度特征",城市森林在沿样带移动过程中,大致呈"V"型分布,其景观比例在城市外边缘处最大;在景观水平上,城市森林在中心城区分布最少,但较为集中,破碎化程度不高,形状比较规则,在向边缘区移动的过程中,其分布趋于零碎化,形状趋于自然。

摘  要：
Based on theory and methodology of landscape ecology,in this paper,it used the forest management inventory of Changsha in 2003 and TM image of Changsha which had been get in 2003,gradient analyzed the landscape pattern of urban forest in Changsha fringe areas by using the 3S techniques,and then grasped the situation of urban forest space landscape pattern in Changsha and it's basic characteristics.Study results show that: At the level of class,urban forest landscape showed respective gradient characteristics along the transect,and was obviously "V" distribution,the proportion of the landscape at the city fringe area was the biggest;At the level of landscape,urban forest landscape distributions in the city center were small,but they were more concentrated,degree of fragmentation was lowly and had comparison rules shape.The more close to the city fringe area,the more degree of fragmentation,and the shape becomes more natural.
