海南大田国家级自然保护区海南坡鹿容纳量的研究

ESTIMATING CARRYING CAPACITY OF HAINAN DATIAN NATIONAL NATURE RESERVE FOR ELD'S DEER

以坡鹿采食的植物资源贮量及坡鹿日采食量的方法，估测海南大田国家级自然保护区的坡鹿容纳量。围栏内的坡鹿容纳量是每公顷ｌ·０１－１．４２只，围栏外每公顷１．４０－１．８５只。在这一密度下，种群数量保持稳定，种群增长率等于零。为尽快增加种群数量改变坡鹿的濒危状态，应将坡鹿的数量控制在１／２容纳量以内，即围栏内容纳１５２—２１３只，围栏外容纳６９０—９０９只。应尽快扩大围栏面积并严格控制割取鹿茸的雄鹿比例，以保存种群的遗传多样性。

The carrying capacity of Hainan Datian National Nature Reserve for eld's deer was estimated during dry season, 1993. Available food resources of eld's deer were the only factor to be considered in this project. The carrying capacity of eld's deer in the area within the enclosure was 1. 01-1. 42/ha, and 1. 40-l. 85/ha. in the area out of the encosure. The population size would be stable under this density, the birth rate would be equal to death rate. In order to increase the population size in short term time period, the goals of deer population management in the Nature Reserve should be to keep up the population size within 1/2 carrying capacity, i. e. that the deer would not be more than 152-213 and 690-909 individuals within and out of enclosure.
