查询词典 runoff

The amount of pesticide and herbcide applied was less, the pure quantity was only 1. 9kg/ha which is about 40％ of the Jinlin Province's average. In farmland, There are 26700ha of solonetz and solonchak, and 289700ha of salinized soil with the high content of salts. The salt content in the surface is 1％-2％ in soda meadow solonetz, 1％-4％ in sulfate meadow solonetz, below 0.7％ in meadow solonchak generally, and below 1％ in salinized soil. The runoff and the return flow from above lands have high content of salt and high output load of the soluble salt.

吉林西部耕地中有2.67万hm〓的盐土、碱土和28.97万hm〓的盐碱化土地，这些盐土、碱土及盐碱化土地中均含有较高的盐分，其中苏打草甸盐土表层含盐量1％～2％，硫酸盐草甸盐土表层含盐量可达1％～4％，草甸碱土含盐量一般。7％，来自于这些土地的地表径流和农田回归水中盐分含量高，可溶盐的输出负荷大。

In recent years, the forever-lasting Taiwan and green architecture have become a major topic in our country. In order to resolve the runoff of rainwater resource, to prevent the spoliation of ecology and to reduce the effect of heat island, to search for the suitable mix design of the pervious concrete for Taiwan is not a small issue. Pervious concrete pavement is air permeable and water permeable, the soil underneath can be kept wet and rainwater can quickly filter into ground, so the groundwater resources can renew in time. It improves the environment of road pavement and also possesses many other advantages that improve city environment at drainage, sound absorption and skid resistance, and is suitable for the rainy and humid environment in Taiwan area. However, its high air voids results in low strength, the surface layer of highway pavement was seldom used pervious concrete due to heavy traffic loading.

近年来国内以打造永续台湾与绿建筑为未来努力的方向，为解决雨水资源流失、环境生态破坏及热岛效应扩张，研发本土透水混凝土实有其重要性，透水混凝土铺面可以使空气与水自由地有效的渗入，地下土壤可保持湿润，雨水也能够快速渗入地面至地下水，地下水资源或水位能即时更新，它改善道路铺面的环境，其它的优点尚包括具有良好排水、噪音吸附与车辆抗滑能力，适合铺设於台湾多雨多湿之环境，由於透水混凝土孔隙率较高，其强度低於一般混凝土，应用於重交通量公路面层因此受到局限。
