乡土阔叶树造林效果分析评价

Analysis and Evaluation of Afforestation Effect of Native Broad-leaved Trees

目的:研究乡土阔叶树对环境的影响,分析造林效果。方法:首先采用分别区域对比法分析各个造林指标之间的关系,其次,采用区域实测法,采集乡土阔叶树生长参数,分析影响生长的相关因素,最后采用综合分析法对测量区域的阔叶树进行研究,判定相关生长因素对实际造林效果的影响,观察病虫害情况。结果:研究区域的乡土林场不适宜栽种木芙蓉,更适合栽种广玉兰,在栽种时应尽量避免高温天气对其造成的影响,可以应用补植造林法进行造林维护。结论:积极进行乡土阔叶树造林可以避免乡土环境持续恶化,对保证乡土造林区生态环境,促进生态多样化发展有重要价值,也为乡土阔叶树种培育有一定的参考作用。

Objective:To study the impact of local broad-leaved trees on the environment and analyze the afforestation effect.Methods:firstly,the relationship between various afforestation indexes was analyzed by regional comparison method.Secondly,the regional measurement method was used to collect the growth parameters of local broad-leaved trees and analyze the relevant factors affecting the growth.Finally,the comprehensive analysis method was used to study the broad-leaved trees in the measurement area,determine the impact of relevant growth factors on the actual afforestation effect and observe the situation of diseases and pests.Results:the local forest farm in the study area is not suitable for planting hibiscus,but more suitable for planting Magnolia.The impact of high temperature weather should be avoided as far as possible,and the supplementary afforestation method can be used for afforestation and maintenance.Conclusion:the active afforestation of local broad-leaved trees can avoid the continuous deterioration of local environment,which is of great value to ensure the ecological environment of local afforestation area and promote the development of ecological diversification.It also plays a certain reference role for the cultivation of local broad-leaved trees.
