| 摘要: |
| 本文论述了洞庭湖区湖洲湿地生态系统的演变过程、综合开发途径及其措施。研究表明, 洞庭湖湖洲湿地生态系统在各种外界因子特别是泥沙在湖盆的强烈沉积作用下, 其洲滩面积、洲土质量、生物资源以及人类活动都呈现明显的演变过程。对已经形成的湖洲, 要在不影响洞庭湖泄洪、航运和控制血吸虫病的前提下, 以湖洲高程为主要参照物依次实施湖草安全开发、获苇深度开发、荻林生态开发和产品加工开发, 同时辅之以必要的综合开发配套措施。 |

| Abstract: |
| Dongting Lake，the second largest freshwater one in China，covers 37360km2 with 9. 8%of theareabeingmarshland.Inthepresentpaper，theresourceevolution，integratedexploitation approach and measure of its marshland damp ecosystem are stated.The resultsindicate that the acreage , soil fertility, biological resources and human activities have changedremarkably due to the effects of many external factors(especially silt deposition in the lakebasin)on the marshland ecosystem.With the prerequisites of floodway，shipping and snailfever control，the exploitation of formed marshland should be based on the marshland altitude，and the projectincluding lakegrass safety-exploitation，reedintegrated-utilization andreed-forest ecological exploitation and product process should be carried out in proper order. |
