The ability of forest for climate conservation

本文对森林的气候保护能力进行了以下三项研究。1)地表温度与土地利用的关系：利用Landsat数据推导了林地与其他土地利用的地表温度变化方程。当土地利用方式由森林变为农田时，利用该方程可以计算出地表温度约为4-5个C。2)毁林引起的地表温度变化：利用NOAA/AVHRR数据，对比了毁林区与毁林区地表温度。燃烧区地表温度比林区地表温度高6.0℃左右。3)毁林对泰国、加里曼丹和宁夏地区气温分布的影响：在泰国和老挝之间的毁林区出现了约5-6个‰的高温。

The following three studies about the ability of forest for climate conservation were performed. 1)The relation between surface temperature and land uses: A equation for surface temperature changing from forest land to other land uses were derived using Landsat data. Surface temperature was able to calculate about 4-5ﾟC high by the equation, if land use changes from forest to crop field. 2)Changing of surface temperature due to deforestation: Surface temperature between forest area and burnt area were compared using NOAA/AVHRR data. Surface temperatures on burnt areas were about 6.0ﾟC higher than that on forest areas. 3)Effect of deforestation on distributions of air temperature in Tailand, Kalimantan and Ningxia in China: About 5-6ﾟC high air temperature appeared in area of deforestation between Tailand and Laos.
