浅谈西干渠二所沿线洪水资源化

洪水资源化是我国新时期治水理念更新的产物,需要我们改变过去洪水"入海为安"的思想,需要统筹安排防洪减灾和调洪兴利,综合利用系统论,风险管理,科学调度等现状理论,管理方法,科技手段和工程措施,实施有效的洪水管理,适度承担风险,规范人类行为,给洪水以出路和蓄滞空间,在保障防洪的同时,留住洪水资源,造福人类.     

2003 中国水势

近年来，我国南涝北旱的尴尬现状十分突出，水资源利用与防洪之间有着尖锐的矛盾。1998年的特大洪水给了我们许多启示——一方面是水的大量流失，另一方面是严重的干旱和众多城市的缺水。中国的水利工作者开始思考这样的问题：洪水究竟能给我们带来什么?水利专家们近囚在天津指出，中国应该尽快扭转治水思路，“善待洪水”，充分利用雨洪资源，人与水只有和谐相处，才能保证大自然生态平衡，建设美好家园，享受美好生活。

也说防风氏被杀

相传大禹治水来到大越的时候(今浙江绍兴),为了继续更好地治理洪水,决定在茅山召集各地诸侯计功封爵,并商讨今后治水的良策。于是就有了《左传·哀公七年》所载"禹合诸侯于涂山,执玉帛者万国"的盛典。防风氏接到通知后,却没能及时与会,大禹心想:"如再不治他,洪水难以根治,

谁能保护食品安全

破坏性的高速增长、一盘散沙的小农经济、九龙治水的多头管理、对环境的麻木,一起构成了低劣食品的保护伞。降低发展速度,修复环境,建立环保利益链条,让信用得到收益,建立现代农业,改变国民素质,是食品安全必不可少的基础。

Urban flood control strategy based on new relationship of human and flood

China is one of the countries with the most serious flooding disasters.In China,above 70% of big cities,50% of population and 75% of industrial and agricultural output value are distributed in eastern coastal areas with serious flooding.Therefore,enhancement of theoretical study and experience summarization of urban flood control is of great theoretical and practical significance.As economy is developing rapidly,urban scale is expanding fast,and urban flood control stand is promoted.Urban flood control calls for new concept and methods.This paper makes a systematic summarization of concept evolution and advanced methods concerning urban flood control at home and abroad.The concept of urban flood control has transformed from simple flood control and drainage to coexistence with and use of flood.Flood control measures have transferred form emphasis upon engineering ones to priority to both engineering and non-engineering ones,with special attention to ecological flood control,such as making full use of ecological revetment,ecological realignment of a river,multi-objective management of urban flood detention region,turning flood into resources and utilization of wetlands.     

Reference Dependence Effects on WTA and WTP Value Functions and Their Disparity

In this study we investigate two reference dependence effects in a choice experiment. The first is the effect of the well-known distinction between gains and losses, the second is the effect of changing the reference value on willingness to pay (WTP) and willingness to accept (WTA). The latter has to our knowledge not been studied before. We hypothesize that there are differences between WTA and WTP, and that both value functions and their disparity are affected by the absolute value of the reference point. We test our hypotheses using a choice experiment with trade-offs between changes in flood probabilities and costs. The choice experiments elicit WTP and WTA, using two flood probability reference values, yielding four separate value functions. Our findings show that a substantial WTA–WTP disparity exists, and that this disparity increases when moving away from the reference point. Also, both WTA and WTP value functions are affected by the flood probability reference value, and the WTA–WTP disparity increases when the flood probability reference point increases. Both findings suggest that welfare effects caused by changes in public good provision depend not only on the direction of change (loss aversion), but also the reference value. Moreover, our results show that the latter effect is larger for losses than for gains. We introduce the concept of reference point updating as a possible explanation for these findings.

基于生态系统服务空间流的洪涝调节 服务需求制图与生态空间优先级识别

中国快速城市化地区面临严重洪涝风险和洪涝调节 服务供需空间的分离。为识别在满足洪涝调节服务需求方面重 要性高的生态空间以纳入保护的优先级,提出了一种在生态空 间中绘制洪涝调节服务需求的新技术：基于生态系统服务空间 流,利用流量、流边界、流方向、分配原则及其修正因子4个 多维指标,表征将服务需求从建设空间向生态空间分配与投射 过程的关键环节。结果显示：面积大、人口密度高的建设空间 存在高需求流量;借助水文空间流,服务需求由建设空间被分 配至同一集水区内具有洪涝调节能力的生态空间中;被投射为 高服务需求的生态空间大多规模较大或紧邻高需求的建成空 间。通过控制流量、扩展流区域、增加流方向和提升生态空间 服务供应能力,能有效调控投射于生态空间内的洪涝调节服务 高需求。     

Flood Risk Information,Actual Floods and Property Values: A Quasi‐Experimental Analysis

Hedonic property price analysis tells us that property prices can be affected by natural hazards such as floods. This paper examines the impact of flood‐related variables (among other factors) on property values, and examines the effect of the release of flood risk map information on property values by comparing the impact with the effect of an actual flood incidence. An examination of the temporal variation of flood impacts on property values is also made. The study is the first of its kind where the impact of the release of flood risk map information to the public is compared with an actual flood incident. In this study, we adopt a spatial quasi‐experimental analysis using the release of flood risk maps by Brisbane City Council in Queensland, Australia, in 2009 and the actual floods of 2011. The results suggest that property buyers are more responsive to the actual incidence of floods than to the disclosure of information to the public on the risk of floods.     

黄土高原丘陵沟壑区生态城市指标体系与评价研究--以甘肃省陇西县为例

本文在甘肃省陇西县2002年的社会、经济统计数据和实地调查数据的基础上，运用运动层次分析法，分生态、社会和经济3个子系统，共选取37个指标，对地处我国黄土高原生态脆弱的陇西县作了县域范围内的生态城市评价，评价结果为：陇西县目前的生态城市化指数只有48.66％。同时，文章采用常规情景的方法，结合国家建设小康社会的标准和陇西地方实际，对未来10年到20年的生态城市指标作了规划，得出的结果是：2010年陇西生态城市化指数将达到68.25％，2020年达到75.93％，到2050年达到83.61％。文章最后提出了陇西县建设未来中等城市的建议和具体措施。

Building a 3-D model of a flood basalt: an example from the Etendeka, NW Namibia

Flood basalts represent large outpourings of lavas which often cover, and interact with, sedimentary basins. For this reason areas with significant flood basalt cover are often targets for hydrocarbon exploration. Problems exist, however, when trying to image sediments and structures in offshore regions covered by basalts. Here we present preliminary 3-D models of the Etendeka flood basalt province from NW Namibia, which can act as an aid in understanding the internal and external architecture of the flood basalt cover. Satellite images, digital elevation models, measured geological logs, sections and maps, are used to create the geological model. Models are presented in 2 parts; 1) models created using topography with images such as Land Sat and geological maps draped over them, and 2) a 3-D model of key lava and sediment surfaces in the basin as defined by measured geological sections. Initial results show a palaeo-volcanic feature early in the flood basalt history which is onlapped by later Iavas. The modelling also allows a simple correction for post emplacement subsidence by assuming an original sub horizontal position for the first basin wide silicic flow unit.     

旅游产品的静态博弈经济分析

改革开放以来,我国旅游业一直保持着快速增长的态势,经济效益和社会效益十分明显。旅游产品在旅游业发展中起了至关重要的支撑作用。本文基于Hotelling产品决策模型,以青岛和三亚海滨旅游产品为例进行了静态博弈经济分析,得出结论,即旅游产品差异化程度越高,旅游产品间价格竞争越弱,则城市对旅游者的垄断力越高,利润也越高。因此,突出旅游产品的差异,树立旅游产品特色,打造品牌旅游产品成为当前旅游业发展的一项重要任务。
