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

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.
