摘要
近两年来,随着天然林保护工程的顺利实施,扩大了造林面积,年平均造林面积达万亩以上,增加了该地区植被覆盖率和促进林区经济协调发展。但经调查,近几年造林成活率较差,平均初植成活率在70%～80%,未达到天保工程造林质量要求,现就影响其造林成活率的因素讨论分析,并提出相应对策。
Abstract. Afforestation area has been increased greatly in the past years due to the implementation of natural forest protection. The investigation of afforestation, however, showed that survival rate was lower,with initial planting survival rate at 70% to 80%, without meeting the requirement of project.The paper analyzed the factors affecting the survival rate in afforestation. Counter-measures for improvement were suggested.
