Sediment and contaminant, during moving and migrating process in nature, mainly depend on moving flow fully to wash and carry it. A rainfall on the slop flow together into the ditch in a layer of thin overflow. The discharge of that enlarges the capacity of erosion and sandment-laden per volume rapidly. In order of to describe two types of the status during runoff process for loess region in this article, first of all, one should divide a basin into surface erosion zone and heavy erosion zone, and apply directly to the net rainfall process caculated by hydrological basin model for arid region, covering on the slop of surface erosion zone, and set up the surface erosion equation of bed load transport in which sediment are eroded in stratificate status during laminar overflow process on the slop and the diteh erosion equation of suspended load transport gone through heavy erosion zone during runoff process in the ditch and river system. This paper presents the viewpoint that sediment yield ofabasin is mainly caused by the modl of these two kinds.Finally, combining the caeulating example of sediment yielded from Cha Ba Gou basin, this paper summarizes the effect of the basin geographic elements to sediment yield of the basin.

泥沙及污染物质在自然界搬运、输移,主要依靠运动水流冲刷、挟带来完成.在坡面上一场降雨以薄层漫流形式汇集到沟壑,其流量集中,单位水体侵蚀、挟沙能力迅速增大.本文为了描述象这样的黄土地区径流形成过程中两种不同形式,首先将流域分为面蚀区和重力侵蚀区,然后直接应用干旱地区流域水文模型计算的净雨过程覆盖在坡面面蚀区域上,建立了在坡面层状漫流过程中它所形成的泥沙层状剥蚀、推移质运动方程以及地表流汇集到沟壑河网后,穿过重力侵蚀区的沟蚀悬移质运动方程.本文在这里指出流域产沙主要是由这两种方式引起的. 最后结合岔巴沟流域产沙计算的例子,本文总结了流域下垫面因素对流域产沙量的影响.

Based on the data of species of Fagaceae, surveyed from 15,000m~2 of69 plots in 12 counties and cities, in mid-subtropical evergreen broadlea-ved forests in northern and central Fujian Province, and of the agglo-merative analysis between the similarity indexes of some counties andthe different species of the family these species may be divided into twoarea groups, i.e. the northern Fujian area group and the central Fujianarea group. According to the analysis of the different species of the family inthe surveyed counties by the polar ordination method, it is clear that inthe mid-subtropical zone of Fujian, they are not alike all the areas: alti-tute increases positively with rainfall and negatively with temperature.Therefore this shows the comprehensive effect of the geographic elements.(temperature and rainfall) on the ecological distribution of these species.Analysis of the ecological amplitudes among these trees indicates thatCastanopsis eyrei, C. fargesii, C. fordii and Cyclobalanopsis glauca arebroad-distribution species, but Castanopsis sclorophylla and C. jucunda arerepresentative species of the northern Fujian area, and C. carlesii and C.kawakamii are representative species of the central Fujian area.

福建中亚热带闽北部、闽中部两亚地带,气候条件与植被类型特征均有一定的差异,而其常绿阔叶林中占绝对优势的壳斗科树种的分布,具较明显的水平地带性规律。本文为进一步探讨其分布特点,据该地带12个县(市)的共69处调查样地、15000m~2面积的壳斗科树种数据,采用调查县(市)间及其树种间的重要值相似性指数作聚类分析,将全地带壳斗科主要树种的分布划分为闽北部与闽中部两个区域类群。用调查县(市)及树种作极点排序表明,不同地理分布区各树种的数量和长势等特征反映出纬度与降水量呈显著正相关而与温度呈显著负相关。它显示出福建地理因素中的温度与降水量对树种分布的综合作用效果。树种分布的生态幅分析表明,全地带的甜槠等4个树种属于较均匀广布种,而苦槠、乌楣栲与米槠、赤枝栲等,分别属于该地带的闽北部与闽中部亚地带的区域代表种。
