休闲旅游农庄水生态承载极限研究——以四川省为例

随着生活水平的提高,人们越来越向往绿色生态的生活方式,然而,生态环境已经伴随着经济的发展不断恶化,水资源利用也逐渐偏离可持续发展理念。文章以可利用水资源量、人口和城镇化、农业用水、生态环境用水作为关键因素构建了休闲旅游农庄的水生态承载极限定量计算模型。通过对主要部门用水量和相关指标数据调查和总结,根据定量模型计算结果显示,总体看,四川省水生态承载能力足以维持远景规划,其中,成都平原、四川盆地、川东平行领谷区、川中丘陵区、川西高原等5个地区的水生态承载力分别为15 628万人、10 215万人、8 301万人、5 504万人、4 809万人。

CARRYING CAPACITY OF WATER ECOLOGICAL IN LEISURE FARM---A CASE STUDY IN SICHUAN

With the improvement of people′s living standard, more and more green ecological ways of life have been widespread concerned. However, ecological environment has been deteriorated accompanying by economic de-velopment and the utilization of water resources does not conform to the idea of sustainable development. In this pa-per, the quantitative calculation model of the water ecological carrying capacity of leisure tourism farm was estab-lished taking the usable amount of water resources, population and urbanization, agricultural water use, ecological and environmental water as the key factors. Based on the investigated and summarized water use in major depart-ments, the model results showed that the water ecological bearing load can meet the long-term planning in Sichuan province, which was 15628 million people, 10215 million people, 8301 million people, 5504 million people, 4809 million people, in Chengdu Plain, Sichuan Basin, valley area in east Sichuan, hilly area of central Sichuan Basin, western Sichuan Plateau region, respectively.
