Water Resources Supporting Capacity Of New-type Urbanization In Gansu Province

Under the guidance of theories of new-type urbanization and supporting capacity of water resources,describe and analyze the current situation of urbanization and water resources in Gansu Province and various regions.the entropy evaluation method was used to measure the urbanization system and water resource system respectively.On this basis,the supporting capacity between urbanization and water resources was measured by using the compound coordination model,so as to scientifically evaluate whether the current situation of water resources in Gansu Province and various regions can support the construction of new-type urbanization in Gansu Province.And the related recommendations of the coordinated development of the two to promote the development of new-type urbanization in Gansu Province.The study found that Gansu Province and various cities and towns have made some progress in terms of population urbanization level,economic development,infrastructure and public services,and ecological environment protection.However,there are still problems of uneven development in various cities and counties.In terms of water resources utilization,the total amount of water resources in Gansu Province has changed year by year,and the degree of utilization of water resources,utilization efficiency have improved.However,the distribution of water resources in various cities and cities is extremely uneven,and there arealso differences in utilization management.There are also different levels of water shortage in Gansu Province and various regions.The research result showed that from 2000 to 2013,the supporting capacity of the water resource system to the new-type urbanization development of Gansu Province was continuously increasing;from 2014 to 2017,the overall supporting capacity of water resource system to new-type urbanization of Gansu Province showed a fluctuating declining trend,indicating that with the acceleration of urbanization construction,the contradiction between new-type urbanization and water resources began to appear.The water resource supporting capacity distribution for all the regions in Gansu Province in 2017 is shown as follows.Wuwei city,Baiyin city,Linxia city,Dingxi city,Tianshui city,Longnan city,Pinglian city and Qingyang city were relatively unsupported,while the six regions including Jiuquan city,Jiayuguan city,Jinchang city,Zhangye city,Lanzhou city and Gannan city were basically supported.There were no relatively supported and very supported regions,indicating that the supporting capacities of water resources in all the regions of Gansu Province were at a low level and the supporting capacity of most regions was undesirable.Fitting the supporting capacity of water resources in Gansu Province from 2000 to 2017,the relationship between the supporting capacity of water resources in Gansu Province and time series showed a inverted U-shape curve.And using SPSS22.0 to predict thewater resources support capacity of Gansu Province in 2018-2021,it is found that the supporting capacity of the future water resources will continuously decrease,indicating that the contradiction between new-type urbanization and water resources will be further upgraded.
