基于水质—生态体系的昌吉地区水资源承载力研究

新疆昌吉地区水资源短缺、利用率低、时间空间分布不均严重影响区域经济可持续发展,为研究该地区水资源状况,基于水质—生态体系对昌吉地区水资源承载力进行研究。通过构建基于水质—生态体系水资源承载力分析模型,导入昌吉地区水资源承载力影响因子参数,完成了昌吉地区水资源承载力分析。为保证建立的水资源承载力分析模型有效性,同时进行仿真实验。结果证明:建立的水资源承载力分析模型具有有效性,基于水资源承载力分析结果,提出昌吉地区要合理开发和利用水资源,改造和完善灌区工程设施,提高灌溉工程的灌溉面积和灌溉水的利用率,大力推广节水技术,发展节水型农业,提高节水意识,从而实现生态环境、社会、经济的持续协调发展。

合肥市水资源供需分析及可持续利用规划研究

以合肥市水资源与开发利用状况为研究基础,系统地分析了合肥市水资源的开发利用潜力。运用水资源供需平衡基本理论,定性与定量相结合,依据不同水平年合肥市社会经济发展规模,对合肥市水资源供需进行预测并进行水资源承载力分析。客观评价合肥市不同水平年水资源配置,确保水资源的开发利用在资源和环境承载能力允许范围之内;从宏观的角度对有限的水资源进行科学规划、优化配置、高效利用和节约保护,最后提出保障合肥市供水安全的保障措施与建议,确保区域协调可持续发展。

内蒙古锡林郭勒盟西片区水资源承载能力分析

锡林郭勒盟(以下简称"锡盟")西片区水资源不足,时空分布不均,主要的工业区及居民区,集中分布在面积有限、水资源有限的几处河谷平原上,工业生产与居民生活用水矛盾尖锐,依靠现有的用水模式,不仅使西片区人口、经济和社会的发展面临着巨大的困境,也给环境造成了巨大的压力,工业用水已经达到了极限承载能力。为支撑地区经济发展,科学决策提供依据,文章分析该地区水资源承载力情况。

Relation between Economic Development Level and Resource and Environment Carrying Capacity of Central Area of Yunnan Province Based on Decoupling Analysis

Based on the decoupiing theory and method, an indicator system was built for the relation between economic development level and resource and environment carrying capacity. And the study was carried out on decoupling degree and temporal changes of economic development level and resource and environment carrying ca- pacity in the central area of Yunnan Province. Results indicated that （i） the economic development level and resource and environment carrying capacity in the central area of Yunnan Province mainly experienced strong decoupling, weak decoupling, and ex- pansive negative coupling, and in general it was strong decoupling, and it took on re- verse ＂N＂ in temporal changes. （ii） Change rate of economic development level in the central area of Yunnan Province was greater than zero, but the amplitude of change was not large, while the change rate of resource and environment carrying capacity was negative in 2007-2008, and it was positive in the rest years; from 2007, it took on gradual expansion trend, and scissors difference gradually increased after experi- encing reverse ＂V＂ change. （iii） The strong decoupling was the main situation and it reached the peak value in T5 period and T6 pedod.

Integrated Water Resources Carrying Capacity in Tongzhou District,Beijing City

目前,通州区已被定为北京市的新的发展中心,但水资源短缺和污染已经严重限制了当地的可持续发展。本文以可持续发展为原则,基于"自然—社会"水循环,提出了通州区水资源综合承载力量化模型。根据通州区的未来发展规划,设计了3种情景来提高该地区的水资源综合承载力。研究表明水资源短缺严重制约了通州区的城市化进程和可持续发展,外调水、本地区节水和控制污染是解决通州区水资源短缺的有效途径。
