%X Taking Chaohu Lake as an experimental site,unify the orbit water quality monitor data,using the simple regression and multivariate regression,the semi-empirical models for determinating chlorophyll-a concentration in Chaohu Lake are developed by relating the MODIS 250 meter resolution wave band combinations to chl-a measurements.Then,the distribution of blue-green algal bloom in Chaohu Lake is mapped.The intensity,place and distributed scope of this blue-green algae bloom reflected clearly.The results of this study show that MODIS image data is useful in Monitoring blue-green algal bloom in Chaohu Lake.The ratio of band 2 to band 1 (r2/ r1) with 250m resolution is suitable to retrieve chl- a concentration because it is well related with chi-a measurements(R= 0.9093).
