空间统计分析在林业中的应用

空间统计分析在不到 5 0年的研究和实践中 ,已发展成为研究自然界具有随机性和规律性变量的普遍性的科学方法 ,在国内外诸多领域都有成功应用的实例 ;然而 ,空间统计分析在国内林业中应用才刚刚起步 ,绝大多数林业工作者或科研人员对空间统计缺乏基本的了解。本文首先简要介绍空间统计分析的有关概念、基本原理及其特点 ,同时对地统计学与地理信息系统以及与经典统计学的异同进行分析。结合林业领域特点 ,从森林土壤、物种空间分布、森林干扰、林分因子、种子资源等几个主要方面 ,综述国内外林业领域应用空间统计分析的现状。最后指出在林业领域中应用空间统计分析存在的困难与问题 ,并展望了在林业领域中应用空间统计分析的前景.

Application of Spatial Statistic Analysis in Forestry

In research and application of spatial statistic analysis in the last less than 50 years, it was already developed a universal and scientific method of researching the natural variable with randomicity and regularity, which had many successful examples in domestic and overseas many fields. However, the application of spatial statistic analysis in domestic forestry just started, and most of forest works or researchers were short of understanding for spatial statistic analysis.This paper first briefly introduced the related concept, the basic principle and the characteristics of spatial statistic analysis, and then similarities and differences between spatial statistics and geographical information system and between spatial statistics and classical statistics were analyzed. Combining the characteristics of forest field, the current situations on the application of spatial statistic analysis in domestic and overseas forest field were summarized from the aspects including forest soil, spatial distribution of species, forest interference, stand factor and seed resources. Moreover, existent problems and difficulties in the application of spatial statistic analysis in forest field were presented, and the prospects for the application of spatial statistic analysis in forest field were discussed.
