基于凉山州退耕还林工程中补植补造项目的思考

Thinking About the Reforesting in the Engineering of Converting the Farmland into Forest in Liangshan Prefecture

补植补造在凉山州退耕还林工程中发挥了重要作用,就其原因主要是造林时气候、立地条件等七大因素的限制作用;据植被恢复等理论和产业结构调整原则,凉山州退耕还林补植补造时应充分应遵循适地适树、调整和优化林种树种结构等七大原则;合理布局,分年度实施补植补造,经5~8年的有效管护,使全州森林覆盖率增加0.8个百分点,实现生态、社会、经济效益的有机统一。

The reasons that reforesting had played an important function in the engineering of converting the farmland into forest(ECFF)were the seven limiting factors of that the climate, the site conditions and so on in Liangshan prefecture. Based on the theory of vegetation restoration and the rules of production structure’s adjusting, the reforesting should follow the seven rules of that trees fit site conditions, adjusting and optimizing the structure of tree species and forest stand,and so on in the ECFF of Liangshan prefecture. Reasonable arrangment, actualizing year by year and 5-8 years’efficiency protection will be the plans to increase the forest cover rate of Liangshan prefecture by 0.8%,and at the same time to unify the ecological effects,the social effects and economical effects together.
