Abstract: As an important part of the natural ecological environment system, forest plays an important role in protecting the "diversity and balance" of forest species and maintaining the stable development of forest ecological environment. Nowadays, due to the long-term impact of environment and climate change, the forest diseases and insect pests are more and more serious, which has a serious impact on the balanced development of the whole natural ecological environment. It is very important to further protect the existing forest ecological resources by constructing a complete and practical control plan for forest diseases and insect pests in a scientific way.
