基于突变理论的区域地下水资源开采阈值研究

Research on regional groundwater resources exploitation threshold based on catastrophe theory

本文以辽宁省台安县为研究基点,探讨了人类活动对地下水资源开采阈值的影响。以人类活动对水资源的影响程度为状态变量,水量指标为主控制变量,经济活动为次控制变量,利用突变理论中的尖点突变模型计算求解出水资源系统达到平衡时的地下水供应量,即为当地地下水资源开采阈值。

In the paper, Taian County in Liaoning Province is regarded as a research base. The influence of human activities on groundwater resources exploitation value is discussed. The influence degree of human activities on water resources is regarded as the state variable. Water quantity index is regarded as the main control variable. Economy activity is regarded as the secondary control variable. The cusp catastrophic model in the catastrophe theory is utilized for calculating and solving the groundwater supply when water resources system is balanced, namely local groundwater resources exploitation threshold.
