中文摘要：

从景观生态学出发，建立区域生态承载力指标体系；以杨庄河工业区为研究对象，采用主成分分析法和逐步回归分析法定量分析了区域生态承载力的动态变化特征及变化原因。结果显示，区域生态承载力1999--2001年呈持续下降趋势，2001年以后逐步回升，但仍处于不可承载状态，石化工业的开发建设继而加大对资源的不可持续利用是生态承载力下降的主要原因。

英文摘要：

On the basis of the principles of landscape ecology, a indicator system of regional ecological carrying capacity was proposed. Taking yangzhuanghe industrial park for an example, based on large data and district characteristics analysis, the regional dynamic change and the reason of ecological carrying capacity for petrochemical industry construction was studied. The results showed that the trend of ecological carrying capacity continued to decline in 1999--2001, and gradually to bounce back after 2001, but still in unbearable state, and the increased human activity thereby increasing the unsustainable use of resources was the main reason for ecological carrying capacity decrease.
