摘要

[目的] 探索空间异质性较大的岩溶区的土壤温度空间自相关尺度及其空间结构

分析影响典型岩溶区土壤温度空间结构的主要环境因子。[方法] 应用经典统计学方法与"3S"技术。[结果] 不同深度土壤温度的空间分布均存在高度的正向全局空间自相关和明显的空间聚集区

各深度土壤温度的空间孤立区分布较少;影响不同深度土壤温度空间分异的环境因子排序为:土壤厚度>坡度>植被覆盖度>高程。[结论] 土壤厚度对土壤温度的影响

实质上是岩溶环境的综合反映。坡度、高程等地形因子是造成土壤逆温结构的主要影响因素。此外

土壤温度的空间分异还会受到植被覆盖"遮蔽作用"或"保温效应"的影响。

Abstract

[Objective] This paper aims to demonstrate the spatial autocorrelation and the pattern of soil temperature

and to find the main environmental factors.[Methods] Classical statistics and 3S technology were used.[Results] The spatial distribution of soil temperature in different soil depth showed a general highly positive spatial autocorrelation and had obvious spatial clusters

nearly no spatial isolated distribution was found. The impacting factors of spatial distribution of soil temperature in different soil depth ranked as:soil thickness

slope

vegetation coverage and altitude.[Conclusion] The influence of soil thickness on soil temperature

essentially

is the comprehensive reflection of karst environment. Terrain factors

like slope

elevation and so on

are the main factors influencing soil inversed temperatual structure. In addition

the spatial heterogeneity of soil temperature also been affected by "covering" or "heat preservation effect" of plants.
