摘要
基于水资源与社会经济协调发展模型,选取平水年份的2005年为例对安徽省水资源与社会经济协调发展空间分布进行分析。研究发现:安徽省地市间水资源与社会经济的协调度差异明显:以高开发利用极不协调(5个城市)和低开发协调(6个城市)两个类型最为突出;其他地市基本以中度开发协调或基本协调为主。人均GDP最高的合肥、芜湖、马鞍山、铜陵和淮南5市是高开发利用极不协调区;人均GDP低的阜阳、亳州和宿州3市正处在低开发协调区;另外处在低开发协调区的宣城、池州和黄山3市是人均水资源量在全省最高的3个区。进一步对比淮北与芜湖发现,两市水资源和人口数量相当,但协调度迥异,其GDP和用水量相差都在2～3倍。可见,社会经济发展水平差异以及由此带来的用水差异是水资源与社会经济协调发展差异的根本原因。与已有的研究成果对比发现,协调度与社会经济干旱指标在度量水资源支持社会可持续发展上结论基本吻合,尤其在经济发展水平较高区域表现出更高的一致性。
The model of coordinated development of water resources and economy was used to investigate the spatial distribution of coordinated development of water resources and economy in Anhui Province using the data in the normal flow year of 2005. The results showed that the regional difference of the coordinated development degree of water resources and economy is signifi- cant between different cities in Anhui province. There were two outstanding types： extremely incoordination with high utiliza- tion ratio of water resources（five cities） and coordination with low utilization ratio of water resources（six cities）, and other cit- ies showed coordination with moderate utilization ratio of water resources. The five cities （Hefei, Wuhu, Maanshan, Tongling, and Huainan） showing incoordination with high utilization ratio of water resources had the highest per capita GDP , whereas the three cities（Fuyang, Bozhou, and Suzhou） showing coordination with low utilization ratio of water resources had the lowest per capita GDP. Moreover, the three cities（Xuanchen, Chizhou, and Huangshan） showing coordination with low utilization ratio of water resources had the highest per capita water resources. Further, Huaibei and Wuhu had similar population and water re- sources quantity, but the coordination degree was significantly different,and the differences of GDP and water consumption be- tween the two cities were about 2 to 3 times. Consequently, the different level of socio-economic development and the resulting water consumption difference were the basic causes for the difference of coordinated development between water resources and social economy. Compared with previous studies, the results in this study were in good agreement that the coordination degree and the indicator of socio-economic drought are two main indexes to measure the sustainable development of water resources, es- pecially in the area with a higher economic development level.
