It is reported that 70 percent of MPM has had a history of asbestos contact. There is a thin layer of crocidolite in the surface soil somewhere in Da Yao County of Yunnan province. Because the natives don"t know asbestos" hazard, clay containing asbestos was dug in order to make asbestos stoves, build roads, brush walls, combining the crusts destruction, much deforestation makes asbestos explosion .

云南省大姚县某些地区地表中夹着薄薄的一层青石棉，由于当地居民不知道其危害，大量开挖含青石棉的粘土做石棉炉、铺公路、刷墙等，地表破坏，以及大量砍伐森林，造成水土流失，石棉暴露，含棉岩自然风化，雨水冲刷成为天然污染源。

Numerical analysis is performed to study the effects of some physical parameters to the displacement of surface soil.

通过数值计算分析，进一步研究了各物理参数对地基动力响应的影响规律。

The results showed that soil type had significant effects on the root morphology and nodule traits of test varieties. In alfisol, the root dry mass, root length, and root surface area of test varieties were greater at the fifth trifoliolate stage and bloom-beginning stages while smaller after seed-beginning stage, compared with those in mollisol, and the average root diameter after seed-beginning stage was higher in alfisol than that in mollisol. Soil type did not affect root-shoot ratio. The nodule number after seed-beginning stage was much smaller in alfisol than in mollisol, while the nodule fresh mass and the mass per nodule were in adverse.

结果表明：土壤类型对大豆根系形态及结瘤性状均有显著影响，在第5片复叶展开期和初花期，暗棕壤的根系干质量、根长和根表面积低于黑土，而在鼓粒初期后高于黑土，暗棕壤的平均根直径在鼓粒初期后也高于黑土，但土壤类型对根冠比的影响不大；暗棕壤的根瘤数在初花期后明显低于黑土，但根瘤鲜质量和单个根瘤质量高于黑土。

In this paper the related data of underlying surface at home and abroad and the common criterions of land use classifications were utilized, the actual conditions were also combined and the underlying surface feature, including land use, soil feature and terrain elevation, over Heihe River and it's neighbourhood have been classified into two kinds of grided data with high resolution (about 3 km×3 km and 6 km×6 km respectively).

本文综合了国内外诸种有关资料，借鉴了国际上较通用的下垫面特征分类标准，也结合黑河地区下垫面的实际情况，对HEIFE试验区及其邻近地区的下垫面特征(包括地表特征、土壤特征及地形高度)进行归纳分类，形成了两种高分辨率(分别约为6km×6km及3km×3km)的下垫面特征的格点化资料，可供该地区地气相互作用研究用。
