Classification system of inter-silva grasslands in Northern China
摘要
Abstract
Inter-silva grasslands,serving as a critical transitional zone between forest and grassland ecosystems or grassland within forest land,have significant ecological importance.However,a widely accepted concept and a unified standard classification framework for inter-silva grasslands is not well recognized,neither domestically nor internationally,and this lack of recognition leads to constraints on their ecological conservation and rational utilization.Based on a comprehensive analysis of the state-of-the-art research findings from around the world along with extensive field surveys in typical forests of northern China,this study proposes a scientific definition of inter-silva grasslands.Inter-silva grasslands are defined as grassland patches of varying sizes and forms that occur within or on the edges of large forests,or that are interspersed with sparse trees or shrubs.Considering the geographic environmental features,usability,and visibility derived from medium to high spatial resolution remote sensing imagery,this classification system for northern China's inter-silva grasslands includes four classes:forest gap grasslands,forest edge grasslands,sparse forest grasslands,and shrub grasslands,with further subdivision into twelve distinct subclasses.This study provides a conceptual framework to support the ecological protection and sustainable use of inter-silva grasslands in northern China.关键词
