| 摘 要： | 以MODIS遥感影像为基础,在各种气象参数和遥感空间建模的支持下,应用定量遥感反演技术,获取了松嫩平原植被覆盖度、土壤湿度、陆面温度和植被净初级生产力四种生态环境要素的空间分布栅格影像。通过应用GIS空间分析功能,总结了各种生态环境要素的空间分布规律,并对植被覆盖度与土壤湿度、陆面温度和植被净初级生产力之间的相关性分别进行了定量研究。

| Abstract: | On the support of meteorological parameters and remote sensing spatial modeling,this paper based MODIS image and used remote sensing quantitative retrieval technique to take the system analysis about the spatial distribution rule of the four ecological environment elements vegetation cover,soil moisture,land surface temperature and vegetation net primary productivity.Looking from the result,the four kind of environmental essential factors in Songnen Plain present the gradual change tendency from Northeast t... |
