Abstract
The paper built the evaluation index system and grading standards for the vulnerability ecological environment and the carrying capacity of water resources in karst areas, established the evaluation model for the ecological environment vulnerability and carrying capacity of water resources based on GRNN and RBF neural network theory, constructed using interpolation network training sample of a typical karst area Xichou County planning level in different eco - environmental vulnerability evaluation and analysis of water resources carrying capacity. The results showed that: (1)the eco-environmental vulnerability of Xichou County in different level years is between moderate and strong, the water carrying capacity is fundamental to carry and can carry, the evaluation results accord with the status quo Xichou County and can provide reference for the karst regional ecological environment and water resources development and utilization. (2) the evaluation results of GRNN and RBF network model for the fragile ecological environment and water resources carrying capacity in Xichou county level is the same, indicating that the study to establish a fragile ecological environment and water resources carrying capacity of assessment models and evaluation methods is reasonable and feasible, compared with BP and other network algorithm , GRNN and RBF neural network model are possessed of fast convergence, high prediction accuracy, less adjustable parameters and differcult to fall into local minimum and so on.关键词
