摘要: 采用地形位指数综合描述深圳市龙华地区的地形差异,并在此基础上,利用无量纲的分布指数对景观组分的空间分布特征进行半定量分析。结果表明,地形位指数可以综合地反映地形条件的空间分布和差异信息。分布指数用于描述某种组分的实际分布与标准分布的差异,可以排除面积的干扰,为各种比较分析创造了条件。研究时段内龙华地区景观组分在地形位梯度上整体分布格局的复杂性显著增加。人为景观改造活动主要表现为一种中尺度土地利用结构调整行为,并有助于对不同地形条件下的土地利用进行更加严格的分工,地形差异则是大尺度景观整体格局形成的基本骨架。

Abstract: Terrain niche was used to describe the terrain difference of the Longhua area in Shenzhen special economic zone, and nondimensional distribution index was used to semiquantitatively analyze the spatial distribution characteristics based on the remotely sensed interpretation maps of landscape elements.Distribution index can describe the difference between the actual distribution and the standard distribution of a landscape element, excluding the disturbance of the area therefore availing kinds of comparative analyses.The complexity of holistic distribution pattern on the terrain niche gradient of the landscape elements significantly increased from 1988 to 1996.Land use and structure regulation activities on Meso-scale are the main human transformation activities, which contribute to finer division of land use of different terrain conditions.The different terrain conditions frame the landscape pattern in the large scale.
