基于NDVI的宁夏植被覆盖变化与气象因子相关性研究
本文主要是基于MODIS—NDVI时间序列遥感数据和宁夏10个气象站点资料，在Geographic Information System（GIS）技术和统计分析软件SPSS的支持下，分析2000—2010年间宁夏银川NDVI的变化规律，探讨NDVI与气象因子之间的相关性，建立起它们之间的线性回归模型。

Abstract In recent years, the rapid development of economy accelerates the process of industrialization and the unreasonable exploitation of natural resources leads to the destruction of the ecological environment. Both of them speed up the rate of global climate change. Vegetation just like a natural tie which links soil, atmosphere, moisture and other elements .There are mutually dependent and interactional relationship between vegetation and climate. The normalized difference vegetation index (NDVI) is the optimal indicator factor of plant growth state and spatial distribution of vegetation density. It can basically reflect the status of the change of vegetation coverage, at the same time, respond to climate change. Therefore, people used to use it as the measure parameters when they make a research of the growth condition of vegetation.
In this paper, I use MODIS - NDVI time series of remote sensing data and the information of 10 weather stations in Ningxia. Based on the Geographic Information System (GIS) technology and the support of Statistics Package for Social Science(SPSS), I analysis the change rule of NDVI from 2000 to 2010 in Ningxia yinchuan, discuss the correlation between NDVI and climatic factors, and finaly establish the linear regression model between them.
