乡村森林生态适宜性定量评价技术研究
Quantitative evaluation of rural forest-ecological adaptability
【摘要】 森林生态适宜性评价是科学合理地开展森林经营管理活动的基础工作。针对乡村森林经营的特点,以森林资源二类调查资料为基础,根据森林树种的生态学特性和经营管理范围内的生态环境条件,进行森林生态因子划分、权重确定及其适宜性分级与定量化,运用综合评价法原理提出生态适宜性指数来定量表达林分和区域森林生态适宜性。应用实例结果表明,浙江省上虞市岭南乡区域森林生态适宜性综合指数为0.57,接近适宜水平,表明现实森林类型及其分布基本上与生态环境条件相符合。生态适宜性指数涵义明确,评价技术简便可行,结论直观且具可比较性,对乡村森林经营规划和管理具有实践指导价值。
【Abstract】 Evaluation of rural forest-ecological adaptability is the basis for scientific and rational forest management.Based on the characteristics of rural forest management and forest management inventory,ac-cording to the ecological characters of forest species of trees and eco-environment conditions in rural areas,the research divided the forest ecological factors,measured the power coefficient of each forest ecological factor,graded and quantitized the forest-ecological adaptability.The comprehensive evaluation principles were used to define the forest-ecological adaptability indexes to analyze and describe the forest-ecological adaptability of stand and research district.The application of this method in Lingnan town,Shangyu City forest management showed that the forest-ecological adaptability index here was 0.57,close to adaptation level;the real forest group and its spatial distribution was in line with the ecology conditions.The forest-ecological adaptability indexes were clearly defined,convenient,straight forward,and practical for the forest management and planning in rural areas.
