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。

The data used in this paper was obtained from the comprehensive oceanographic survey during the First Chinese National Arctic Research Expedition in Chukchi Sea and Bering Sea in July and August 1999. The characteristics of ecological groups, species composition, horizontal and vertical distribution of Chaetognatha in both Chukchi Sea and Bering Sea are described and the relationships of Chaetognatha density and some other environmental factors are discussed.

根据 1 997年 7─ 8月我国首次北极科学考察期间，分别在楚科奇海和白令海进行海洋综合调查的资料，分析了这两区毛颚类种类组成和生态类型的特征、丰度的水平分布、层状分布和昼夜垂直分布。

Based on analytical results of X 2 and r formulae,plants of shrub layer can be divided to 4 ecological species groups: Cytisus fish+Juniperus communis...

对测定结果的生态学意义进行了分析，依据测定结果，将形成灌木层的植物划分为4个生态联结种组：俄罗斯金雀花＋璎珞柏、欧洲白蜡＋欧洲白榆、疣枝卫矛＋欧洲荚迷＋黄忍冬＋欧榛子＋黑茶镳子＋稠李＋欧洲赤杨。

Through experiment of 15N microplot showed that: gaseous losses of fertilizer nitrogen was 1.259g·m~(-2), soil residued nitrogen was 1.023g·m~(-2) in Ecological Balanced Fertilization plot, monitored at the same time that chemical nitrogen fertilizer was almost no leakage because there was illuvial layer in the depth of 100～120cm in this area.

通过15N微区试验测得草甸黑土生态平衡施肥区肥料氮气态损失为1.259g·m~(-2)，土壤残留为1.023g·m~(-2)，同时监测到，在该地区100～120cm土层处由于有淀积层的存在，化学氮肥几乎没有渗漏。通过设置不同施氮水平试验，结果显示：大豆播种后，田间土壤氨挥发累积量随氮肥用量增加而增大。
