The benthic assemblage eco-positions of brachiopod communities in the early Early Carboniferous were between BA1 and BA2, and there were no BA3-BA5 deep-water communities in this area, which indicated that the sea water depth in this period was commonly less than 10 m.

In the light of the paleoenvironmental significance reflected by the radiolaria, graptolite, brachiopod,sponge spicule and the rock character, its suggested that the greyish green mudstone at the basal WufengFormation of the Goujiaya section would be probably deposited in 60 to 100 meters deep water, theGuanyinqiao bed in 50 to 80 meters deep, and the radiolaria-bearing silicalite from Wufeng Formation inwater with 200 to 400 meters deep. Combining the above-mentioned water depth with the sea-level changecycles, the change range of every one of the 5 cycles could be further conjectured. They were in ascendingorder: 20~120 m, 80~130 m, about 150 m, 50~250 m, and in excess of 200 m.

根据放射虫、笔石、腕足类、海绵骨针以及岩性等对古环境的指示意义,认为五峰组底部灰绿色泥岩段产出时水深约60-100m,观音桥层水深约50-80m,在晚奥陶世最大海侵期(对应于T.typicus亚带下部),水深约400m,五峰组含放射虫硅质岩沉积时最小水深约200m,结合以上海平面变化的5次旋回,从而推算出各旋回海平面的变化幅度:在第①旋回,海平面变化范围大致为20~120m;在第②、第③和第④旋回中,海平面变化分别为80~130 m、大约150 m和50~250m;第⑤旋回的海平面升降幅度大于200 m。

It was found that, for the control treatment the average runoff depth was 3.72mm per 10mm, the water loss index was 37.2%, the average soil erosion was 43.6 kg*hm-2*10mm-1, and the soil erosion modulus was 7.42 t*km-2*a-1, which are all high in the 4 treatments. For the other three treatments, the surface runoff and the average soil erosion amount were 2.20%-67.08%and 43.81%-90.83%lower than those of the control, respectively. The most effective pattern for soil conservation was the artificial forest with underbrush treatment, and the best water conservation pattern was the treatment of planting tea bush on contour terrace.

结果表明,CK的平均径流深度为3.72 mm/10 mm,降水流失率为37.2%,平均每10mm降雨的土壤侵蚀量为43.6kg*hm-2,年土壤侵蚀模数为7.42 t*hm-2;其它3个不同植被覆盖处理的地表径流量比裸地对照降低2.20%~67.08%,平均土壤侵蚀量减少43.81%~90.83%;林下地表覆盖处理的保土效果最好,等高梯田种植茶树处理的保水效果最好。

The research results show:(1) we combine time series method with the dispersed Markov Chains theory of stochastic process, and present a Markov Model based the time series analysis for predicting the precipitation for groundwater resources evaluation. Results show that the time series-Markov Model is efficient, and it has higher accuracy than that of the single model of time series;(2) started from the systematic point of view, we analyze the metabolic process of groundwater, establish the ultimate metabolic equation of groundwater for protecting the water resources, and discuss the value of reducing evaporation for making full use of the water resources;(3) Through a theoretical analysis of the results of the experiments, we draw a conclusion: the critical depth on evaporation of groundwater is in step with the height of the maximal capillary rise of media.

In the area of sharp depth change, the pattern of average current field varies sensitively with wind speed change, while in the area of flat and gentle bottom, insensitively. The current direction in shallow water was consistent with the direction of the wind, while against the wind direction in deeper water and responded slowly.

在水深水平变化较大的区域,垂直平均流场结构对风速变化的响应较为敏感,易形成环流,浅水区垂向平均流向和风向一致,深水区则和风向相反;水深变化较小的水域,流场结构对风速变化的响应则较为迟钝。
