查询词典 alluvial fan

Tectonic subsidence play dominant role in their geometric shapes, basin fillings, sequence evolution and sediment distribution in the Wushi Sag. Outline of the sequences are in shape of box-wedge or sheet-wedge and boundaries of sequences are varied from bilateral fault to monoclinal fault overlap, so that the sequences show distinct semigrabens which overlay in different ways. Seven sequences were formed in different stage of tectonic evolution. The sequence of SQ1 formed in initial rift stage and deposited alluvial sequence. Sequences SQ2-SQ4 developed in intense rift stage and sediment lacustrine sequence. Sequences SQ5-SQ7 formed in late period of rift before thermal subsidence and deposit mere and delta sediment. The place adjacent to the synsedimentary fault is the subsidence center and depocenter; meanwhile, controlling fracture migrates in horizontal made subsidence and sedimentary center of the sag changed.

构造沉降是控制层序几何形态，充填叠置方式、演化及沉积体系分布的最重要因素：凹陷由多个半地堑在不同层序发育时期以不同方式叠置联结而成；受断层控制，层序外部形态有箱状-楔形、楔形-席状披覆型，边界终止方式有双断终止型、单断终止超覆型；不同构造演化阶段层序内部充填的沉积体系各具特征，初始断陷阶段的SQ1沉积冲积层序，强烈断陷阶段的SQ2-SQ4充填湖相层序，晚期断陷阶段SQ5-SQ7内部充填浅湖和河流三角洲沉积；同沉积断层陡坡带沉降迅速、可容纳空间快速增长，是凹陷的沉积和沉降中心，断陷期主控断裂活动时间和空间的变化导致了凹陷沉积和沉降中心的迁移。

In this study, a culture with bitter gourd seedlings (Momordica charantia L.) was conducted in a field (clay slate noncalcareous alluvial soil, Tsp2), located in Wanli, Miaoli. There kinds of composted animal manure (chicken compost, cattle compost, and cattle-hog compost) as well as chemical fertilizer were applied to different treatment plots to investigate and compare their effects on soil fertility and the growth, and on the quality of bitter gourd. One check treatment was also conducted.

A soil wind erosion experimental plot was set up in the alluvial sandy land of old yellow river,which is in Xiajin County of Shandong Province,and the soil wind erosion quantity was tested with measuring scale method in the observation farmland shelter-forest network and the comparison place.

在山东省夏津县黄河故道冲积沙地建立土壤风蚀试验区，采用标尺法对3种网格的农田防护林和对照地的土壤风蚀量进行观测，测定结果表明：农田防护林网可明显减少风蚀损失，其中，130m×300m林网相对于对照减少土壤风蚀量81%，260m×300m林网相对于对照减少78%，300m×400m林网相对于对照减少75%，即随着网格面积的增加对风蚀量的影响越来越小。
