对长江上中游流域生态重建问题的思考

Discussion on Tactics for Eco Reconstruction of Upper and Middle Reaches of Changjiang River Basin after 1998′s Flood.

长江中上游流域灾后生态重建的重点是：在上游恢复与重建森林生态系统，实行“封山育林，退耕还林”的方针，加强定位试验研究，完善森林自然保护区网络，控制水土流失；在中游重建湖泊生态系统提高调蓄功能，整治河道圩垸增强泄洪能力；

On the bases of the State Council′s policy, the following suggestions for ecoreconstruction in Upper and Middle Reaches of Changjiang River Basin have been proposed:for the Upper Reaches, to rehabilitate and rebuild forest ecosystems, to implement government policy of “Sealing and Reforesting of Hills; Stopping Cultivation for Afforestation”,to enhance the research works of the fixed ecological monitoring stations, to perfect the forest nature conservation network, and to control soil erosion; For the Middle Reaches, to restore lake ecosystems for improving their regulating and storing function and capacity, to maintain and renovate existing watercourses, dams and dikes so as to buildup their sluicing capacity, and to put water conservancy projects and measures into effect so as to guarantee the local safety during the flood season.
