Related Problems and Countermeasures of Drought-Resistant Afforestation Technology in Forestry Engineering
This paper analyzes the related problems of drought-resistant afforestation technology in forestry engi-neering,and analyzes the specific solutions according to the actual situation,aiming at providing a reference for the implementation of drought-resistant technology in forestry engineering projects.A demonstration area of eco-logical engineering construction in Lanzhou City of Gansu Province was selected as the sample site,and the appli-cation status of drought-resistant afforestation technology in the demonstration area was analyzed by quantitative evaluation.The problems related to drought-resistant afforestation technology were summarized,and the survival rate,preservation rate,annual high growth rate and replacement rate of forest trees in the forest area were com-pared after specific solutions were formulated.The quantitative evaluation showed that the problems of drought-resistant afforestation included water shortage,improper selection of drought-resistant tree species,poor effect of drought-resistant afforestation technology,mismatch between management mode and afforestation technology,and high requirement of afforestation standardization.In March 2020,the drought-resistant afforestation technology will be improved,and the survival rate of trees and the preservation rate of trees will be improved.The average annual growth rate of forest tree was increasing gradually,and the replacement rate of forest tree was decreasing gradually.There are many problems related to drought-resistant afforestation technology in forestry engineering in Lanzhou,Gansu Province.According to the specific situation,it is necessary to formulate specific countermeas-ures according to the environmental characteristics of different regions and the actual situation of regional devel-opment,so as to promote the growth of trees and achieve the goal of drought-resistant effect.
