目前,在我国关于生态农业的思想非常活跃,支持生态农业的人越来越多,搞生态农业试验的科研单位也与日俱增。在这一形势的推动下,江苏省盐城市环保部门,于一九八三年春就向各县、区提出了开展生态村试点建设的意见,想从基层做起,在实践中探索经验,办出一批符合国情的生态村、生态乡,以至生态县来。一年多来,我市七县一区为搞好试点,做了大量的对基本情况的调查和技术方案的研究工作,取得了一定效果。目前已有十多个不同类型、不同程度的生态村(场、圃)和200多个生态户。 相似文献

吴县黄桥镇张庄村,位于苏州著名风景区虎丘山上。经过十几年的改革开放,这个村走出了一条生态村发展之路,由一个比较落后的村庄变成了水泥公路贯穿东西,居民楼房一排连着一排,一幢幢豪华型厂房拔地而起的新型农村。1994年工、农、渔三业总产值为2.47亿元,4项效益2005万元、全村劳动力收入达5250元。1987年以来,连续荣获省、市、县“文明单位”、“农村经济建设先行村”’。张庄村之所以能够迅速发展.是因为在治理和控制工业污染、重视生态环境建设方面立足长远,科学规划,狠抓落实.注重效果.创出了“以养鱼起家。农业安家、工业… 相似文献

ABSTRACT. A multiple-outfall system for cooling water disposal which is distributed along the direction of stream flow is analyzed. The results provide a simple method of preliminary design of a cooling water discharge outfall system and for a quick extimate of water quality of a polluted stream. It is shown that a properly designed distributed discharge system is capable of preventing serious pollution due to localized discharge of wastes and waste heat; however, the final design of the discharge system should take into account alternative schemes of waste heat disposal and their economic consequences. 相似文献

ABSTRACT. Flood detention reservoir design is a common problem encountered by engineers and others involved with water resources problems. This paper presents a method by which the volume of flood storage required for a single reservoir or a series of reservoirs may be estimated without using numeric flood-routing techniques. The proposed procedure requires a minimum of computations and is most applicable to preliminary design situations where a high degree of accuracy is not required. 相似文献

ABSTRACT: This paper describes a procedure to design pluvial drainage systems in such a way as to prevent large excavation volumes and erosive velocities. To this end the storage capacity of the channel system is taken into account. In a preliminary step, the procedure employs an approximate method to determine the channel dimensions. Therefore, the dimensions are adjusted by means of a numerical method of solution of the unsteady flow equations. An example is included. 相似文献

Rapid Assessment of Hydrologic Performance of Low Impact Development Practices under Design Storms 下载免费PDF全文
Yang Yang Ting Fong May Chui 《Journal of the American Water Resources Association》2018,54(3):613-630
Low impact development (LID) practices are often applied to compensate for surface imperviousness caused by urban development. These practices can mitigate flood risk by reducing runoff volume and peak flow and by delaying the time to peak flow. To select a suitable LID practice type and its surface area during the preliminary design process, it is necessary to rapidly estimate the hydrologic performance of various LID designs under design storms. This study provides a method and a toolbox for rapid assessment of the hydrologic performance of various LID practices, which can be useful to developers for establishment of preliminary LID designs. The hydrologic performance of three common types of LID practices (i.e., green roofs, bioretention cells, and infiltration trenches) under various design storms is first simulated using the Storm Water Management Model (SWMM). The results are then presented as performance curves on a unit storage basis. Look‐up tables are further developed to assist the comparison and selection of the LID alternatives for various hydrologic performance targets. To facilitate SWMM modeling, a MATLAB toolbox is developed to automate the process of input modification, model simulation, result extraction, and postprocessing. Finally, the sensitivity of the look‐up curves to design storm types and design specifications of bioretention cells is also analyzed, and the assumptions used in the development of these look‐up curves are validated. 相似文献
