The improved entropy method was used to determine the weight, the Technique for Order of Preference by Similarity to Ideal Solution(TDPSIS) was used to calculate the capacity for sustainable development of the cities and counties and sort these cities and counties, and Arcgis10.2 was used to draw the provincewide distribution of the four guidelines. Thereupon, the author reached following conclusions: there was no big regional difference in the sustainable development capacity of cities and counties in Hainan, and they were basically in a general state of intermediate stage in the past four years; Haikou City and Sanya City, as the key cities, had a higher ability of sustainable development and had shown a remarkable capacity to drive the sustainable development of surrounding areas; according to the development level, the four guidelines were in the following order: resource utilization and environmental protection capacity, population development capacity, social support capacity, and economic development capacity.展开更多

In this paper,compilation of rainstorm intensity formula in Luzhai County was taken as the case,revision and compilation techniques and research methods of rainstorm intensity formulas in municipal district and administrated county of Liuzhou were introduced. According to the Design Specification for Outdoor Drainage（ GB 50014-2006,2016） and the Technical Guidelines for Establishment of Intensity-Duration-Frequency Curve Design Rainstorm Profile,historical rainfall data at Luzhai National Weather Station were sampled by using annual maximum method,and sampling time was from1980 to 2016. The period with the maximum rainfall was divided into 11 time intervals： 5,10,15,20,30,45,60,90,120,150 and 180 min. Fitting adjust of rainstorm sample data was conducted by using Pearson-III distribution curve,rainstorm intensity formula was fitted by the least square method,and calculation accuracy test corresponded with the requirement of Design Specification for Outdoor Drainage（ GB 50014-2006,2016）. Conclusions and suggestions were as below： firstly,rainstorm intensity formula was compiled and calculated according to the recommended methods of the Design Specification for Outdoor Drainage（ GB 50014-2006,2016） and the Technical Guidelines for Establishment of Intensity-Duration-Frequency Curve Design Rainstorm Profile,calculation process was normative,and calculation result error met the requirement of the specification. Secondly,sampling by annual maximum method was more suitable for the expression of periodic hydrometeorological law by taking year as reappearance period,and could cause better randomness and independence of statistical sample,and the method was scientific and reliable. Thirdly,rainstorm intensity formula compiled by taking rainfall data in national weather stations of Liuzhou and its administrated counties as the sample could be used in the scope of the local jurisdiction.展开更多

文摘A total of 18 cities and counties in Hainan from 2012 to 2015 were selected as the basic research units to construct an index system for evaluating the ability of sustainable development that includes four guidelines of economic development capacity, population development capacity, social support capacity, and resource utilization and environmental protection capacity.
