摘要
采用基于空间直观种群模型研制的易泛滥成灾野生动物种群预警系统(W SWAP)与景观情景模拟相结合的方法,在凤凰山国家级自然保护区景观分类的基础上,分别设置4个生境面积和生境质量变化的情景,模拟了生境面积和生境质量对野猪种群时空动态的影响。结果表明:随着生境面积和生境质量的改善,野猪种群数量逐渐增加,但生境质量对野猪数量影响有一个限度。野猪种群数量与其生存斑块面积回归关系显著,其主要分布在各情景较大的生境斑块内。空间上野猪集群呈现不均匀分布的特点,随着生境面积和生境质量的改善,野猪集群密度逐渐增加。
Unchecked Spreading Warning System for Wild Animal Population （USWSWAP） was developed based on the spatially explicit population model. Four scenarios for habitat area and habitat quality were set respectively according to habitat classification of Fenghuang Mountain National Nature Reserve in Heilongjiang Province, China. The effects of habitat area and quality on spatio-temporal dynamic of wild boar were simulated using USWSWAP and landscape scenarios. Resuhs showed that the number of wild boar increased gradually with the improvement of habitat area and habitat quality, but habitat quality had a limited effect on wild boar. There was a significant correlation between the number of wild boar and the patch area they lived in, and wild boar populations mainly lived in bigger patches. The block density of wild boar exhibited a non-uniform spatial distribution pattern and increased with the improvement of habitat area and habitat quality.
