By taking the Qianbei 2. 0 ×10⁵t/a bamboopulp paper production projectin Chishui City,Guizhou Province,China for an example,soil and water conservation and ecological reconstruction of the developmentand construction projectin the low mountain and hill region are discussed. Based on the analyses of engineer ing scale,construction methods,and circulation forms,as well as the currentsituation and features of soil and water loss,comprehensive controlling countermeasures of engineering and vegetation and other potential protection measures are presented in accordance with five controlling principles. After the controlling meas ures are finished,soil and water loss in the projectsite can be effectively controlled,destroyed ecological environmentcan be recovered and improved,and the safety of engineering reconstruction can be ensured. Therefore,coordinative and sustainable developmentof society,economy,and environmentcan be achieved.
