孟滦国营林场管理局成立40年来,有林地面积发展到120万亩左右(天然林50.2万亩,针阔混交林30万亩,人工林40.1万亩),其中落叶松、油松纯林38.4万亩。这些人工针叶纯林在发挥生态效益的同时,也获得了较好的经济效益。但弊端是连续发生森林病虫害,严重威胁森林资源的安全。为保护40年的造林成果,加强生态环境建设,必须采取行之有效的对策,以实现森林病虫害的可持续控制。一、森林病虫害的发生与防治现状近年来,该局的森防管理工作逐步走上了规范化的轨道。建立了能够适应当前防治工作需要的森防管理体系。
In the 40 years since its establishment, Mengluan State Forestry Administration has developed about 1.2 million mu of forest land (502,000 mu of natural forest, 300,000 mu of coniferous and broad-leaved mixed forests, and 401,000 mu of plantations), of which 38.4 Mu These artificial conifer pure forests play ecological benefits at the same time, but also get better economic benefits. But the drawback is the continuous occurrence of forest pests and diseases, a serious threat to the safety of forest resources. In order to protect 40 years of afforestation achievements and strengthen the ecological environment construction, effective measures must be taken to achieve sustainable control of forest pests and diseases. First, the occurrence and prevention and treatment of forest pests and diseases in recent years, the council’s prevention and control of forests gradually embarked on a standardized track. We have established a forest defense management system that can meet the needs of the current prevention and control work.
