A STUDY ON CLIMATIC PRODUCTIVITY OF PHOTOSYNTH- ETIC PRODUCTS IN FRESHWATER AREAS OF CHINA
我国淡水水域光合产物的气候生产力探讨

In this paper, some geographical distribution laws of the photosynthetical productivity and the climatic productivity of phytoplankton in freshwater areas of eastern part of China are calculated theoretically with the climato-ecological method. From these results we can know that the annual climatic productivity of primary products in freshwater areas distributes mainly along the latitude and decreases progressively from south to north. Its range of variation is from 1.6-24.4 gC/m2.a. In view of the climatic resource of the photosynthesis of phytolankton, the net fish production in natural freshwater areas at different latitudes must be made in accordance with the different climatic conditions of photosynthesis.
