Determining the Width of Buffer Zone for Open-Forest Nature Reserve in Hunshandak Sandland
摘要
Abstract
Many nature reserves have been established for conserving forests throughout the world.Creating a buffer zone around a core area is often suggested,but determining the width of the buffer zone is a challenge.The soil seed bank is an important indicator for the restoration capacity of a degraded vegetation ecosystem.This could be useful for designing nature reserves.According to the restoration potential and similarity index of seed banks of some sites with different distances from the core zone,the minimum width of a buffer zone can be determined.Different samples,outside of the core zone,with a different distance from the boundary of the core zone were chosen.Analysis of variance was used to analyze species,seedling and seed banks among different samples,the Sorensen's similarity index was calculated.Based on a field survey,the buffer zone of the open-forest nature reserve in Hunshandak Sandland,China has been designed.The minimum width of buffer zone should be 300 m in lowland,600 m in shifting sandy dunes,and 1 000 ～ 1 200 m in fixed and semi-fixed sandy dunes.Seed bank approaches will be useful for determining the buffer zone width of the forest nature reserve and can be applied and extended to the other nature reserves which aim at preserving endangered species/ecosystems and their habitats.关键词
