海丰县水产养殖与越冬黑脸琵鹭种群变化相关性探讨

Relationship Between Aquaculture and Overwintering Black-Faced Spoonbill Population Change in Haifeng County,Guangdong Province

指出了海丰县人工养殖池塘作为黑脸琵鹭重要的栖息地,在维持种群动态平衡上具有重要意义。但由于海丰县水产养殖面积的不断扩大,制约了黑脸琵鹭种群的长远发展。基于此,以海丰黑脸琵鹭为研究对象,探讨了黑脸琵鹭的种群变化与水产养殖面积波动间的相关性,以进一步掌握水产养殖面积的变化对黑脸琵鹭种群动态的影响。结果表明:黑脸琵鹭种群与水产养殖面积具有负相关性(p=-0.822),即水产养殖面积越大,黑脸琵鹭个体数量越少。

As an important habitat for Black-faced spoonbill,the artificial culture pond in Haifeng County plays an important role in maintaining the population dynamic balance.However,the continuous expansion of the aquaculture area in Haifeng County restricts the long-term development of the Black-faced Spoonbill population.Therefore,taking Haifeng Black-faced Spoonbill as the research object,this paper discussed the correlation between the population change of Black-faced Spoonbill and the fluctuation of aquaculture area,in order to further understand the impact of the change of aquaculture area on the population dynamics of Black-faced Spoonbill.The results showed that the population of Black-faced Spoonbill was negatively correlated with the aquaculture area(p=-0.822).That is,the larger the aquaculture area,the smaller the number of Black-faced Spoonbill individuals.
