Effects Of Ecological Planning Measures On Bird Diversity In Shrimp Ponds

Landscape garden planning is address issues that involving the interrelationship between human and ecology.Ecological restoration is key part of landscape in planning,including the restoration of human environment,wetland ecological restoration and biodiversity conservation.China agricultural expansion and urbanization result in the decay of wetlands and associated animals and plants.Migratory shorebirds,an important part of the ecosystem in the field where were rapidly declining in numbers.Birds have the ability that to assess the local ecological environment.To study the conservation effects of ecological compensation on migratory shorebirds,we used the funds from the Eco-compensation Program to rent agriculture ponds at five villages in Guangxi Beilun Estuary Nature Reserve.In winter and spring the lowered depth of water of ponds where were not in use.We recorded the abundance and richness of birds in the ponds and the frequency of birds foraging,as well as the effects of pond water quality on birds over time.We also compared artificial wetlands with natural richness and abundance.We results show that species richness of migratory shorebirds in pumped ponds was about twice as high as in non-pumped ponds,the species abundance was about 10 times higher than that in non-pumped ponds and the pecking frequency of Plovers(Scolopacidae)among migratory shorebirds was higher than the frequency of other migratory shorebirds.At the same time,water quality in aquaculture ponds showed different effects on different bird species.Besides,the abundance and density of migratory birds were significantly higher in natural wetlands than in artificial wetlands(natural wetlands: 1287.82±2503.35,artificial wetlands: 185.22±348.92).Pumped than non-pumped depth was significant,pumped than non-pumped p H don't significant benefits dissolved oxygen,total dissolved solids,conductivity,salinity,and each all water quality was within the standard range.Migratory shorebird species richness was influenced by environmental factors and significant changes were found.According to the results,response variables were used as vectors,species variables,and it was found that the number of species such as Black-headed Gull(Larus ridibundus),Grey Plover(Pluvialis squatarola)and Common Moorhen(Gallinula chloropus)were positively correlated with water depth(cm),species such as Little Ringed plover(Charadrius dubius)and Black-winged Stilt(Himantopus himantopus),were positively correlated with dissolved oxygen(mg/L),and Marsh Sandpiper(Tringa stagnatilis),Dunlin(Calidris alpine)and Kentish Plover(Charadrius alexandrines)were positively correlated with electrical conductivity(ms)and hydrogen ion concentration index(p H).The results of the study suggest that the simple interventions about the dewatering engineering to the breeding ponds,from the aspect of ecological compensation programs,that increasing the use of artificial habitat for migrating shorebirds,especially for overwintering migration.However,artificial wetlands can provide temporary habitat for migrating shorebirds and overall artificial habitat cannot be a substitute for natural habitat.The conservation of natural wetlands and the restoration of artificial wetlands are particularly important in all landscape garden planning.
