Abstract

在四川省植被类型分布数据和地质图的基础上,以200m海拔间隔将四川省划分为36个高度带,在ArGIS10.1软件平台下,利用地理统计功能,分别统计各个高度带内植被类型、土壤类型和岩性的数量,得到植被类型多样性、岩性多样性和土壤类型多样性。三者在四川省的空间分布存在中域效应,即随着海拔梯度的增加,呈现先增大后减小的单驼峰形格局,且三者分布最高的海拔区间分别是1 400m~1 800m、1 400m~1 800m和1800m~4 000m。运用回归分析法对三者之间的关系进行分析研究,可知随着土壤类型多样性或岩性多样性的增加,植被类型多样性随之增加。结果表明:四川省植被多样性与岩性多样性、土壤类型多样性之间存在显著的正相关关系。该研究揭示了四川省植被类型分布与地质背景的关系,为全球气候变化背景下四川省的区域环境建设和生物多样性保护规划提供了科学的理论与数据支持。

Geological factors have great effect on vegetation distribution.Under ArcGIS 10.1platform,Sichuan provincewill be divided into 36belts by 200mintervals.And the geographic statistical function is used to calculate the vegetation typediversity index,lithology diversity index and soil type diversity index of every belt based on the vegetation distribution dada and geological map.The spatial distribution of all the three exist domain effect.With the increase of elevation gradient,its numberpresent increase and then decreases.And the highest elevation of the three is 1 400m~1 800m,1 400m~1 800mand 1 800m~4 000m.The result of using regression analysis method to analyze the relationship among research shows that there was apositive relationship between vegetation distribution and geological background.With the increase of soil type diversity or lithology diversity,vegetation type diversity increased.Paper reveals the relationship between vegetation distribution and geological background and provides scientific theory and data support for regional environment and biodiversity conservation planning under the global climate change background in Sichuan province.
