加快构筑无锡现代化水利的探索

近几年来，我们从无锡沿江傍湖、河道纵横、山区与圩区并存的地形地貌实际出发，从提升防洪设施水平、综合整治内太湖水环境人手，多管齐下启动并实施现代水利建设，取得可喜成效。一是治太四项骨干工程、长江堤防达标建设工程、太湖大堤应急加固工程、城市外排工程、宜兴横山水库除险加固工程等5项流域性重大水利工程建设基本完成。二是综合治理使蠡湖水环境大为改观，     

城市防汛现代化的实践与探索

城市防汛现代化，作为任务命题，应当是一个适应经济科技现代化和城市化进程的内涵较为宽泛的概念。城市防汛，包含城市防洪和排涝两个方面，两个方面紧相联系，密不可分。这两个方面，又关连涉及方方面面，它既要有工程措施，又要有非工程措施；既要有专门的城市防汛设施，又要有交通道路、排水管网、河道河网、雨污分流分治网络等基础设施作为依托；既要有汛期即时的组织指挥，又要有正确超前的气象、水文预测预报和预警措施及通畅的通信网络；既要有城市自身对洪涝灾害的抗防战斗和活动，又要有所在江、河、湖流域范围内水利设施调度配…     

试论城市防洪建设与环境建设的统一性

一乍一看，城市防洪建设和城市环境建设是两个并无干系的命题，因为前者显然属于城市防汛水利的范畴，后者则涵融于城市建设范畴，其实不然。从无锡市丰富多彩的城市工作实践来看，两者之间的内在联系多多。在一定物质财力条件基础上，正确认识和处理好两者关系，对城市可持续发展具有重要意义。首先，城市防洪建设和城市环境建设，都基于城市宏观地理资源和城市基础设施，这种“连根性”往往导致彼此互为依托。每一城市都有自己独特的地理位置、地形地貌以及河道河网组成的内外水环境等等。这些既是城市防洪建设和城市环境建设必须立足的自…     

关于城市河道清淤工作的探讨

很多城市的河道由于生活垃圾、建筑垃圾沉积以及水土流失等原因造成严重的淤泥堆积,加上年久失修,严重影响城市生态环境及人们的健康。文章从实施河道清淤工程的必要性,并结合环保理念分析实施河道清淤对环境造成的负面影响及正面影响对河道清淤工作进行了探讨,从而为更好的开展河道清淤工作,促进城市发展和保障居民健康。     

基于“海绵城市”理念的城市河道生态修复研究

无限制的城市开发建设改变了原有自然水文循环状态,因此造成城市水资源奇缺、洪涝灾害严重、水污染等问题十分严峻。文章针对目前我国城市河道现状,结合国内河道生态治理修复实例,从水文地貌修复技术、河岸护坡修复技术、景观修复设计三方面,探讨"海绵城市"理念下的城市河道生态修复设计思路与技术方案,为城市河道修复,建设可持续的水环境提供参考与借鉴。     

橡胶坝在抚顺市景观建设中的应用

在城市建设中,景观建设是一个重要方面。橡胶坝做为修建于河道上的拦、蓄水工程,具有起落方便,汛期塌坝后不占用河道行洪断面,不影响河道的正常行洪的特点。橡胶坝蓄水形成连续水面,不仅可以为城市提供充足的水源,而且具有美化城市环境,增加城市景观的作用。橡胶坝在城市景观建设中具有广阔前景。     

湖州市小梅港沿岸景观概念设计

1项目概况 小梅港位于湖州市北部.南起白雀塘桥,北至小梅口入太湖,作为苕溪洪水人太湖的通道之一,是湖州城北外围的重要水系,也是湖州城区通往太湖的三条主要水上通道之一.河道全长6.8公里,是城市重要的防洪通道.     

关于对城市河流生态型治理与建设的思考

城市河流是城市空间的重要组成部分,具有多种社会经济功能和环境生态效益.目前我国城市河流存在着河道污染、渠道被挤占及硬化渠化、景观建设的缺乏等问题,通过几年来的工作实践经验,提出了进行排污控制、建设生态河堤、营造生态型滨河景观等项措施.     

我国城市河道综合治理的发展新趋势

河道作为自然界水体流通的大动脉,与城市工业发展、人民日常生活息息相关。随着我国城市建设速度的加快,河道污染较为严重,严重影响城市居民的正常生活,对城市品质提升存在极大的负面影响。城市河道治理的重要性与必要性日益凸显,国家对其的要求也逐渐提高,河道治理既要保证其传统水利功能,又要使其在生态环境上实现人与自然的和谐共存,如何开展城市河道综合治理工作是我国面临的严峻挑战。文章论述了城市河道综合治理的发展历程,并对流域治理PPP模式和城市河道智慧化管理等新趋势进行了分析。     

弹性设计理念指导下的城市河道景观规划设计探索

城市河道是城市环境的重要载体和发展进程的见证者,当代城市河道建设在传统的景观规划设计指导下出现多种问题。鉴于此,文章提出在城市河道景观规划设计中结合弹性设计理念,并探索该理念指导下的城市河道景观规划设计策略。以驻马店市平舆县小清河景观规划设计为例,将弹性设计理念应用在城市河道景观设计中,使城市河道成为生长性景观,为以后城市河道景观的规划设计提供新的思路。     

从效率优先到更加注重公平——改革开放以来我国在公平与效率关系上的演变

改革开放以来,我国在公平与效率关系的权衡上,经历了从"公平优先→兼顾效率和公平→效率优先,兼顾公平→初次分配注重效率,再分配注重公平→更加注重公平"的演变过程。     

Incentives to invest and to give access to non-regulated new technologies

We analyze the incentives of a vertically integrated firm, which is a regulated monopolist in the wholesale market and competes with an entrant in the retail market, to invest and to give access to a new wholesale technology. The new technology represents a non-drastic innovation that produces retail services of a higher quality than the old technology, and is left unregulated. We show that for intermediate values of the access price for the old technology, the vertically integrated firm may decide not to invest. When investment occurs, the vertically integrated firm may be induced to give access to the entrant for a low access price for the old technology. Furthermore, when both firms can invest, investment occurs under a larger set of circumstances, and it is the entrant the firm that invests in more cases. We also discuss the implications for the regulation of the old technology.     

Committing to transparency to resist corruption

This paper studies firms' incentives to commit to transparent behavior in a competitive procedure modeled as an asymmetric information beauty contest managed by a corrupt agent. In his evaluation of firms' offers for a public contract the agent has some discretion to favor a firm in exchange for a bribe. While unilateral commitment to transparency is never incentive compatible, under some circumstances a voluntary but conditional commitment mechanism can eliminate corruption. A low quality firm may prefer not to commit only when the agent's discretion is strong and the market's profitability is small. In that situation, the high quality firms commit when commitment decisions are kept secret, but some conditions on firms' beliefs are required when commitment decisions are publicly announced. A mechanism combining both conditionality and a reward (a transparent selection advantage that needs not be large) allows complete elimination of corruption.     

How to talk to multiple audiences

Stochastic fictitious play (SFP) assumes that agents do not try to influence the future play of their current opponents, an assumption that is justified by appeal to a setting with a large population of players who are randomly matched to play the game. However, the dynamics of SFP have only been analyzed in models where all agents in a player role have the same beliefs. We analyze the dynamics of SFP in settings where there is a population of agents who observe only outcomes in their own matches and thus have heterogeneous beliefs. We provide conditions that ensure that the system converges to a state with homogeneous beliefs, and that its asymptotic behavior is the same as with a single representative agent in each player role.
