卫星遥感湖泊叶绿素分布、初级生产力评估与应用研究,开发出一套直接利用美国陆地卫星TM多波段数字影象信息,测算叶绿素与浮游植物含量的模式与计算机处理的方法.该方法克服了目前国内外已有遥感的局限性,方法简便、覆盖面积大、实现了仅参照少数典型点实测数据,即可利用TM波段亮度值直接计算出大水面的叶绿素与浮游植物含量,并可准确勾绘出水平分布图,是常规方法难以做到的,具有良好的实用性.经过在云南省六大湖泊和江苏、内蒙等湖泊应用证明,具有较显著的经济效益和社会效益.
Satellite remote sensing lake chlorophyll distribution, evaluation and application of primary productivity, developed a direct use of the United States Landsat TM multi-band digital image information, the calculation of chlorophyll and phytoplankton content of the model and computer processing method.This method overcomes the current domestic Outside the limits of remote sensing, the method is simple, covering a large area, achieved only by reference to a few typical point of the measured data, you can use the TM band brightness value directly to calculate the chlorophyll and phytoplankton content of large water surface, and can be accurately drawn The horizontal distribution map is difficult to be achieved by conventional methods and has good practicability.It has obvious economic and social benefits after being proved by the application of six lakes in Yunnan Province and lakes in Jiangsu and Inner Mongolia.
