Abstract: To understand the dynamics of oncomelania population in a river shoal forest-agrosystem and its neighbouring ones, the influence of light, temperature, humidity and soil moisture content on oncomelania density is studied. The results show that the increase of its density during flood period can be attributed to its migration from the neighbouring system, and the sharp decrease of it after flood and before the next one is related to the cultivation and intercropping. Countermeasure for controlling oncomelania multiplication are put forward.

Key words: Forest-agrosystem, Flood period, Oncomelania density, yellow soil, relative yield, long-term application of NPK fertilizer, sustainability index of soil nutrients
