查询词典 basin

With the land use change and the enhancement of human activity, the groundwater pollution index rises from the indirect recharge area via the direct recharge area to the discharge area. The same variation happens from upper reaches to lower reaches in Daxin river basin, a typical karst area in the east of Jinan spring basin where the patterns of land use and human activity changes apparently. There is a close relationship between the groundwater and land use change and human activity.

伴随土地利用方式的改变和人类活动强度的空间变化，地下水质从间接补给区、直接补给区到泉水排泄区，单项污染指数和综合污染指数依次升高；具有典型代表性的泉域东部大辛河流域，从上游、中游到下游，地下水污染物的浓度也渐次升高，且愈往下游污染物浓度增幅愈大，显示出与土地利用方式和人类活动的密切相关性。

Because of the regional difference of soil and climatic conditions, the division of 4 stages of soil moisture circulation is not all the same between different areas; the soil moisture dynamics between different dry farming areas in the Yellow River Basin is contrasted in this report. The results indicate that soil moisture increases gradually from dry semi-arid area to semi-arid area, dry semi-humid area and semi-humid area, and the high value district generally appears during soil moisture resuming period in rainy season or soil melting period. While the low value district appears at the stage of fast evaporation in spring or slow evaporation in autumn; in views of vertical changes of soil moisture, it is showed that the variation range of upper lays is larger than that of lower among the different dry farming areas in the Yellow River Basin.

由于各区域之间土壤、气候条件的差异，各地土壤水分循环4个阶段的划分也不尽相同；黄河流域不同旱作类型区土壤水分动态变化比较结果表明：就季节变化而言(来源：A70b0B0bC论文网www.abclunwen.com)，由半干旱偏旱区→半干旱区→半湿润偏旱区→半湿润区土壤水分含量呈逐渐增加的变化趋势，而且高值区一般出现在雨季恢复阶段或春季土壤融冻返浆时期；而低值区均出现在春季大量蒸发阶段或秋季缓慢蒸发阶段；就垂直变化而言，黄河流域不同旱作类型区土壤水分垂直变化的趋势均表现为上层变化幅度较下层大。

The wavelet variance verification also indicates that the first main period of the runoff of mountainous watershed in the Shiyang River Basin is 30years, and 22years and l5years are the second and third period respectively; 3 Then we also compared the total runoff of mountain watershed with climate factors of Wushaoling which station is in the mountain headstream area, such as precipitation and temperature, the data record that the correlation coefficient of annual runoff and precipitation variation over the upper reaches in the Shiyang River Basin is 0.61 ,which indicates precipitation is the main water recharge of the runoff.

石羊河流域出山口年径流的周期变化与乌鞘岭站年降水量和年均气温周期基本上都能在同一周期上下浮动，其中出山口年径流量与乌鞘岭山区年降水量相关系数为0.61，说明地表径流量主要是由山区降水补给；年径流量与山区年均气温变化呈0.28的反相关，说明该流域近50年来出山口径流与山区气温呈反比，即径流量随年均气温上升而减少，相关性暂时不十分明显。

It was under weak extension during the early to middle Jurassic, with the stretching direction in N-S to NNE-SSW, and the stretching deformation mainly occurred in zones surrounding the Ordos basin.

Occurrence of tectonic heat event on late-Mesozoic in Ordos basin result from intensive thermal mobility of deep lithosphere on the late-Mesozoic,Thermal mobility of deep lithosphere in sourth region is stronger than in north region. Mantle occur underplating and thickness of lithosphere reduce, magma invasion and eruption occur on late-Mesozoic. Ordos basin be in weak extension environment on late-Mesozoic.

鄂尔多斯盆地中生代晚期构造热事件发生的根本原因在于中生代晚期岩石圈深部的热活动增强，盆地南部岩石圈深部热活动性更强，早白垩世鄂尔多斯盆地处于一种弱拉张的构造环境，地幔发生底侵作用，岩石圈减薄，发生岩浆侵入和喷发。

We investigated the wild plant plasm resources under extreme enviroment al conditions at Talimu Basin,Zhunger Basin,on Tianshan Mountain,Kunlun Mountain and the Pamirs recent years,collected above 700 plant specimens,about 410 species They can be devided into 4 types,such as:halophyte resources,xerophyte resources,anti ultraviolet xerophyte resources and anti ultraviolet psychrophyte resource

Based on the Changxing Agricultural Geologic Environment Survey in Zhejiang Province, the paper marks the abnormal plot of some elements in the soil of surface layer in Meishan Basin, such as Cd、Hg、As、Ni、Pb、S、Br、Cl、F, and lays emphasis on the spatial distribution of the abnormalism, and also evaluates the environmental quality of soil and shallow groundwater preliminarily.

Third, introducing the evaluation theory of ecosystem service, it set up an appraisable system of ecosystem service values of water resources, which is specially carried on to Haihe Basin too.

The age of MORB-type metabasic volcanic rocks is(1462± 28) Ma using the SHRIMP zircon U-Pb method.The presence of MORB and IAT assemblages suggests the existence of an ocean basin in Yunkai area,Guangxi,southwestern South China Block during Grenvillian.They probably defined as a part of archipelagic ocean system before South China has formed unified Rodinia during the Grenvillian orogeny.Cathaysia block and Yangtze block have experienced continent-continent collision orogenics behind this ocean basin subducted,and have formed unified Rodinia.
