Abstract

Abstract:

This paper introduces the characteristics and main results of forest inventory system and the ninth inventory work in Jiangxi Province.Based on the results of multi-period forest inventory,the dynamic change of forest resources in recent 20 years is analyzed.In order to facilitate the construction of the National Experimental Zone of ecological civilization in Jiangxi Province,this paper,from the angle of sustainable development,put forward some countermeasures for strengthening the protection of forest resources and forest quality improvement.

Key words: Jiangxi Province, forest resource inventory results, dynamic change, potential analysis, management countermeasure
