江苏盐城国家级珍禽自然保护区调整及其驱动力分析

Readjustment of the Yancheng National Rare Bird Reserve in Jiangsu and Its Driving Forces

摘要: 在确定了盐城国家级珍禽自然保护区调整原则基础上,提出了该保护区的范围调整和功能区划调整方案。调整后,整个保护区范围由调整前的45.30×10⁴hm²减至28.42×10⁴hm²,核心区由调整前的1.74×10⁴hm²增至2.19×10⁴hm²,占保护区总面积的7.71%,缓冲区和实验区分别由调整前的4.67×10⁴、38.89×10⁴hm²变为5.57×10⁴、20.66×10⁴hm²。从自然条件改变、区域种群动态以及保护区与周边地区协调发展3个方面分析了盐城保护区调整的驱动力。

Abstract: Based on the set principles for readjustment of the Yancheng National Rare Bird Reserve(YNRBR),a scheme is put forth for readjustment of its area and functional zones.The readjustment will reduce the total area of YNRBR from 4 530 to 2 842 km²,but expand the acreage of the core area from 174 to 219 km² which accounts for 7.71% of the total area of YNRBR;the buffer zone from 467 to 557 km²,and the experimental zone from 3 889 to 2 066 km².Besides,driving forces of the readjustment are analyzed from the following 3 aspects:changes in natural condition,dynamics of the communities in the region and harmonized development between the reserve and the adjacent regions.
