| 摘 要： | 本文从景观的概念出发，以地理信息系统为支撑手段，开发了空间信息数据库以记录分析福建森林植被景观的块斑，不规划性及景观总体特征，通过定量分析福森林植被的空间格局，说明福建森林植被景观受物理，生物以及社会和经济参数的制约情况，空间数据的对比序列表明，参数中某些参数值存在着空间差异，会导致福建森林景观的变化。

| Abstract: | nder the guidence of the idea of landscape and the method of GIS, the author develops thespatial information database to be used to analyse patches, irregularity and general feature of landscape of forest vegetation in Fujian. It is shown that the complexity of toPOgraphy and disruptionsof mankind are primary physical parameters of controlling ecosystem functions of landscape(suchas motions of water and soil, rainfall and temperature), diversity of living things and efficiencyof soil water. The synthetical characters of landscape calculated reflect briefly the influences ofthose two physical paraneters. StructUre and shape of artificial vegetation (especially forpaddy) suit fundamentally to toPography. Both southern subtropical rainforest and middle subtropical evergreen broad-leaf forest exist at lower fractal dimension and simple geometrical Patterns. Their shapes are obviously different from these of toPography condition and structures ofothers landscape tares which are more complex. It indicates that human activities have produceddeep influences on the structure of the two zonality landscapes.The author shows spatial distribution of forest vegetation by GIS, surveys spatial strUctureof forest vegetation by quantitative models. From those it can be explained how the forest vegetation in Fujian is restricted by physical, biological, social and economic factors. |
