摘  要:
采用遥感信息解译了中国北方地区植被覆盖度 ;通过植被覆盖度推算出水土保持作用系数 ;保土作用系数与降水蒸发差呈负相关 ,与植物初级生产力呈正相关 ,其相关性很高 ,可信度均超过 0 .0 1水平。在北方地区保土作用系数有可能成为评价区域生态功能的综合指标。

摘  要:
The vegetation coverage was interpreted by using remote sensing information in northern region of China. The water and soil conservation effect coefficient was also calculated through vegetation coverage. The correlation between water and soil conservation effect coefficient and the difference between precipitation and evapotranspiration was negative. The correlation between water and soil conservation effect coefficient and the primary vegetation potentiality was positive. The significance was more than 0.01 level. So, the water and soil conservation effect coefficient may possible become a comprehensive index to evaluate regional ecological function in northern region of China.
