水土

In recent years The temperature rising in climate and continuous draught, together with the overgrazing and other unreasonable human activities, has resulted in serious eco-environment deterioration, less runoff, water and soil loss, more mudflow, pasture degeneration, land desertification, reduction of biological diversity, etc. This threatens the local agricultural and husbandry production and the people's living, and also restrains the social and economic development.

由于近年来气候升温、持续干旱，加上超载过牧及其他不合理的人类活动，导致生态环境严重恶化，径流量减少，水土流失、泥石流加重，草场退化、土地沙化，生物多样性减少等，使当地农牧业生产和人民生活受到威胁，制约了社会经济的发展。

The measure of the mine ecosystem manage and recover include the manage of mine mullock field and the mine ecosystem recover.

矿山废石场治理措施包括源头治理、水土分流、修建拦土坝等；矿山生态恢复工程一般包括工程性恢复和生物性恢复两个阶段。

This study chose the dahongshan mine which has very important significance to the developing of yunnan iron and steel industry as our work station in which we build six runoff plots according to loss type and chose three place to earth up to observe the rule of the soil moving on the mullock stone and study the eroding rule of the barren side slope with eroding nail experiment.

本研究选择新建的、对云南钢铁工业发展具有重要意义的大红山铁矿进行矿山水土流失研究，按土壤侵蚀类型建立六个径流场进行观测，利用侵蚀钉对人工堆积边坡、裸露自然边坡和公路边坡侵蚀进行研究，在废石场选择三个点进行覆土实验对废石场覆土的潜移和管状侵蚀量进行观测。

Be it poetic experience of certain events or fervent expression of mysterious existence, his works are filled with mysteriousness and passionateness of living creatures, and with in-depth thoughts behind the romantic and magnificent physical appearance, which not only represents contemporary art trends and aesthetic experience, but also well accords with the tradition of Chinese culture, in particular, the romantic Chu-sao culture in the pre-Qin period---- an ancient regional culture which he is related to by birth.

无论是对情境的的诗性体验还是对神秘存在的激情表达，他的作品总是充满着生命和精灵交织的神秘与热烈，在浪漫璀璨的外表下潜藏着厚重的思虑，这不仅与当代艺术主题和审美经验相映照，而且与中国文化传统，尤其是具有浪漫抒情气质的先秦"楚骚"文化的脉络相契合，后者显示了他的出生地的水土渊源。

Our technological equipment is rich, including global satellite positioning system GPS, geological radar meter (SIR-20, EKKO), seismograph, infrared detector (NEC-TH9100), ultrasonoscope, building structure diagnose apparatus, proton magnetometer, atomic absorption apparatus, ion chromatograph, gas chromatography, niton survey meter, and etc.

中心拥有各类先进的检测和探查仪器，如：GPS卫星定位仪、全站仪、数字水准仪、美国SIR-20地质雷达仪、加拿大EKKO地质雷达仪、地震仪、NEC红外热像仪、超声波检测仪、质子磁力仪等物探测量仪器，以及原子吸收仪、离子色谱仪、气相色谱仪、氡气探测仪等化学、放射性检测仪器。同时，不断加大对科研经费的投入，引进和开发地质雷达探测、瞬态面波探测、高密度电法等物理探测、远红外成像检测、GPS动静态定位技术、水土环境监测、研发高难度废水处理工艺、地质灾害防治措施及科技考古技术等新方法。

The results indiceated that Elaeagnus angustifolia is not only a pioneer tree, but also a good food to prevent forming nitrosamine from nitrite in body.

试验结果表明，沙枣不仅可以作水土保持、防沙造林的先锋树种，还由于它富含抗氧化物，可作为人体降低体内亚硝胺生成的良好补充源。
