Behavioral fragmentation of waterfowl habitat and its landscape ecological design in Shuangtai-hekou Reserve, Liaoning, China

--Behavioral fragmentation of wildlife habitat isdiscussed. Using "buffer" module in ARC/INFO, behavioralfragmentation habitat of Red-crowned crane, Saunder's gull,Oriental white stork and Siberian white crane was calculated in theShuangtai-hekou national reserve, Liaoning Province, China. Theresult showed that breeding Red-crowned crane, Siberian white craneand breeding Saunder's gull are very sensitive to fragment factors.Suitable habitat is so little for more than 2000 Saunder's gull tobreed. The reserve only has a capacity of 38 pairs for breedingRed-crowed crane. Two key measures were made. First, dismantles allthe abandoned oil wells and recovers the original ecosystem todecrease the fragmentation effect, directly benefit to breeding ormigration of Red-crowned crane and Oriental white stork. Second,recovers the Suaeda tidal mud flat from artificial shrimp and crabpond in the kernel zone of the reserve to enlarge the habitat areaof Saunder's gull and Siberian white crane.
