Abstract: Climate modeling was carried out by MTCLIM for the up-reaches of Minjiang River. On the basis of data obtained in monitoring stations, the mean maximum temperature, mean minimum temperature and potential evaportransporation were estimated for the modeling period time from July to September,1995. The maximum of the three meteorological indexes all appeared in July and decreased gradually from July to September,with their spatial distribution changing correspondingly to the topographic change of the landscape but the potential evapotranspiration changed differently due to the effect of vegetation. The modeling result was verified by the obtained data in stations. The relative error of mean maximum temperature and mean minimum temperature was minor, while the potential evaportransporation was major. The modeling result was in general acceptable. When combining MTCLIM with GIS, the climate modeling may provide the spatial distribution of climate factors for advanced ecological process study, and also meteorological indexes for distributed watershed vegetation.
