当前我国水资源管理中存在的流域机构权威缺失、条块分割、块块分割和部门分割等体制性缺陷 ,要通过加强流域机构与地方政府协作、建立水资源市场化配置机制、促进流域经济一体化和实现水资源管理职能综合化等措施 ,以此构建水资源管理中的利益协调机制  相似文献   

The History of the South East Asian Peninsular Games,1959–1975     

Peng Han Lim  Mohd Salleh Aman 《国际体育史杂志》2016,33(5):545-568

After the Second World War the Southeast Asian countries of Burma (1948), Laos (1954), Cambodia (1955), South Vietnam (1955), Malaya (1957), and Singapore (1959) sought independence from the British, French and Japanese colonialists. The first post Second World War and post-colonial biannual multisport Southeast Asian Games was held in Bangkok in 1959 among these countries (and Thailand) although they were relatively poor developing countries. Referring to official reports of the eight bi-annual SEAP Games and other sources of information this research studies how the organization of the eight SEAP Games since 1959 contributed to the nation building process of each country and shaped the political landscape. This was carried out by creating a national identity through sports in each country as well as creating a sense of regional cooperation during periods of war, shifting boundaries and identities. This was done through rituals to legitimize newly ascended constitutional monarchies and heads of states, national flags and athletes' national identity during competition. The SEAP Games also gradually opened avenues for women's participation similar to female athletes in the Olympic Games. It also provided opportunities for promising athletes to shine, improve and compete at higher levels at the Asian and Olympic Games.  相似文献   

济南市举办第十一届全运会经济及社会效应研究   总被引：3，自引：0，他引：3  

张志勇 《山东商业职业技术学院学报》2007,7(5):11-18

本文在分析第十一届全运会对济南社会经济发展影响作用的基础上，着重对全运会经济及社会效应进行了理论探讨，认为全运会效应具有很强的正负影响效果。全运会正效应具体表现为经济效应、社会效应、环境效应；负效应表现为虹吸效应、低谷效应和风险效应。应充分利用全运会的正效应，规避负效应。进而提出：为实现全运会经济社会效应最大化，应调整政府在全运会承办中的职能，推行全运会市场化运作；并给出实施第十一届全运会市场化运作的具体建议措施。  相似文献   

龙宫水溶洞的成因分析     

冯开禹 《安顺学院学报》2007,(4)

文章分析了龙宫水溶洞的形成机制,认为龙宫水溶洞是在地层地貌基础、水动力条件和断裂构造等因素的影响下形成的一个地下伏流系统。在新构造运动的影响下,喀斯特作用的向深性不断增强,水溶洞的局部顶板崩塌,使完整的伏流系统分解为五段地下水溶洞,称为"五进龙宫"。龙宫的龙门瀑布与黄果树瀑布在形成机理上有一定的相似性。  相似文献

Perceived health problems in swimmers according to the chemical treatment of water in swimming pools     

Álvaro Fernández-Luna  Pablo Burillo  José Luis Felipe  Julio del Corral  Jorge García-Unanue  Leonor Gallardo 《European Journal of Sport Science》2016,16(2):256-265

The objective of this study was to determine which chemical treatment used for disinfecting water in indoor swimming pools had the least impact on users' perceptions of health problems, and which generated the greatest satisfaction with the quality of the water. A survey on satisfaction and perceived health problems was given to 1001 users at 20 indoor swimming pools which used different water treatment methods [chlorine, bromine, ozone, ultraviolet lamps (UV) and salt electrolysis]. The findings suggest that there is a greater probability of perceived health problems, such as eye and skin irritation, respiratory problems and skin dryness, in swimming pools treated with chlorine than in swimming pools using other chemical treatment methods. Pools treated with bromine have similar, although slightly better, results. Other factors, such as age, gender, time of day of use (morning and afternoon) and type of user (competitive and recreational), can also affect the probability of suffering health problems. For all of the above, using combined treatment methods as ozone and UV, or salt electrolysis produces a lower probability of perceived health problems and greater satisfaction.  相似文献   

Measurement precision of body composition variables in elite wheelchair athletes,using dual-energy X-ray absorptiometry     

Mhairi Keil  Julia O. Totosy de Zepetnek  Katherine Brooke-Wavell 《European Journal of Sport Science》2016,16(1):65-71

The purpose of this study was to assess the reproducibility of body composition measurements by dual-energy X-ray absorptiometry (DXA) in 12 elite male wheelchair basketball players (age 31 ± 7 years, BMI 21 ± 2 kg/m² and onset of disability 25 ± 9 years). Two whole body scans were performed on each participant in the supine position on the same day, using Lunar Prodigy Advance DXA (GE Lunar, Madison, WI, USA). Participants dismounted from the scanning table and were repositioned in-between the first and second scan. Whole body coefficient of variation (CV) values for bone mineral content (BMC), fat mass (FM) and soft tissue lean mass (LTM) were all <2.0%. With the exclusion of arm FM (CV = 7.8%), CV values ranged from 0.1 to 3.7% for all total body and segmental measurements of BMC, FM and LTM. The least significant change that can be attributed to the effect of treatment intervention in an individual is 1.0 kg, 1.1 kg, 0.12 kg for FM, LTM, and BMC, respectively. This information can be used to determine meaningful changes in body composition when assessed using the same methods longitudinally. Whilst there may be challenges in the correct positioning of an individual with disability that can introduce greater measurement error, DXA is a highly reproducible technique in the estimation of total and regional body composition of elite wheelchair basketball athletes.  相似文献   

小良水土流失中气候水文因素影响的灰色分析   总被引：1，自引：0，他引：1

研究了水分胁迫下亚精胺对小麦幼苗相对含水量、叶绿素总量、蛋白质含量和蛋白酶活性的影响。结果显示,亚精胺预处理延缓水分胁迫下小麦幼苗叶片含水量、叶绿素含量和蛋白质含量的下降,抑制蛋白酶活性的上升。表明亚精胺预处理对水分胁迫的小麦幼苗具有防衰抗旱的保护作用。  相似文献
