| 中文摘要: |
| 以河南省新乡市为研究对象，基于支持向量机理论，建立了新乡市水资源承载力评价支持向量机模型，并根据水资源承载力影响因素，提出了8项指标评价体系，利用水资源承载力指数对研究区的水资源承载能力进行评价。结果表明，1995—2008年间，研究区的水资源承载能力指数在0.22~0.55之间，属于弱承载。随着节水型社会建设工作的推进和再生水的利用，研究区水资源承载力指数明显提高，2015年水资源承载力指数可以达到0.6以上。研究结果对促进当地的水资源开发利用，并为类似地区水资源承载力的评价分析提供了新方法。 |
| 英文摘要: |
| Based on the support vector machine （SVM） theory，a SVM model was established to evaluate the water resources carrying capacity in Xinxiang City，Henan Province. The evaluation index system with 8 factors was suggested according to the impact factors of water resources carrying capacity，and the water
resources carrying capacity of the study area was evaluated and predicted. The results show that from 1995 to 2008，the water resources carrying capacity index of Xinxiang was varied from 0.22 to 0.55，which belongs to weak carrying capacity. With the construction of water-saving society and the using of recycled water irrigation，the water resources carrying capacity index of the study area will be significantly improved. The predicted index of this city in 2015 will be 0.6 or higher. This study result is helpful to the management of exploitation and utilization of regional water resources. |
