A new geochemical survey may expose the extent of China's soil contamination problem.

新一轮的全国性的土壤污染状况调查暴露出污染的程度。

In the Geochemistry surveying work, the measurement of trace silver in soil is a very important part.

在地球化学样品调查工作中，土壤中痕量银的测试是整个测试工作的重要组成部分。

Attention should be paid to the mineralization of some dispersed elements such as Ga, Ge and Tl in Langshan polymetallic mining field. The Wulashan-Daqingshan is the favorable area for prospecting greenstone type gold deposit.

调查结果显示，河套地区土壤主要富集Mg、Ca等碱性物质，西部狼山一带的多金属矿区应重视Ga、Ge、Tl等分散元素矿床的研究，乌拉山到大青山一带是寻找绿岩型金矿的有利地区。

Tentatively, this study introduced simple and economical Dynamic Cone Penetrometer and Impact Soil Tester for facilitating the investigation of subgrade and upgrading its quality.

为此，本研究尝试导入简易且低价位之动态圆锥贯入仪与土壤冲击测定器，来调查路基之工程性质。

In this paper,taking several typical control types of Three Gorges reservoir area as the example,the effect factors, characteristics and rules of the soil erosion and its diversification of the soil physical and chemical properties under different vegetation types were studied by large numbers of pilot field survey and positioning observation.

占总面积66.3%的山区旱坡地是三峡库区江河泥沙的主要来源，为了控制三峡库区水土流失，科技人员对三峡库区坡耕地土壤侵蚀进行了大量的调查研究，但对于构建不同植被类型下的水土流失特征及其生态效应研究还停留在定性描述的阶段。

At the same time, we studied population dynamics of seed-eating rodents in the autumn and the following spring. The results showed that, without enclosure protection, most of the seeds were predated due to high predation pressure in the autumn. The emergence rate of seedlings of all the studied species significantly increased under autumn protection, complete protection, and 1-4cm burial under soil covered by litter.

结果表明：秋季鼠类对种子的捕食压力大，使得种子在无保护的情况下很少存活到出苗；而秋季覆网保护和完全保护（覆网一直保留到第二年10月调查时为止）均增加了直播种子的存活和出苗率；将种子埋藏在土壤1-4cm也显著增加直播种了的存活率和出苗率，这与鼠类密度(12%)在秋季显著高于春季(2%)有直接关系。

By using the TM images in 1997,2001 and the spatial analysis methods of remote sensing and investigated by quadrat,the dynamic change of vegetation,land use and soil erosion in the "Shan-Gan-Ning air mass to Yinchuan" natural gas pipeline project region during the period from 1997 to 2001 are analyzed.

基于在中国西北生态脆弱区天然气管线建设的工程实例，利用夏季陆地卫星图像为基本信息源，应用遥感解译分析、野外样方调查等方法，以植被类型、土地利用、土壤侵蚀为基本评价因子，对天然气管线建设前、后项目区的生态环境变化进行了分析研究。
