沙漠化

The role of ecotones in the distribution of Andean birds.

科尔沁沙地沙漠化过程中的物种多样性。

Googling Huangyangtan comes up with a number of reports about anti-desertification measures to be taken there (assuming this is the same Huangyangtan as I have found here). There does seem to be a lot of tree-planting around the facility and the model.

如果google一下Huangyangtan，会出来很多报告关于那里反沙漠化的方法（假设huangyangtan是我找到的这个）好像的确在那个设备和模型周围有很多树。

These projects are: the "three norths" shelterbelts (the western area of Northeast, and the northern parts of North and Northwest China), the shelterbelts along the upper and middle reaches of the Yangtze River, the coastal shelterbelts, the plain farmland shelterbelts, the Taihang Mountains afforestation project, the anti-desertification project, the shelterbelts for comprehensive control in the Huaihe River and Taihu Lake basins, the shelterbelts for comprehensive control in the Pearl River basin, the shelterbelts for comprehensive control in the Liaohe River basin, and the shelterbelts along the middle reaches of the Yellow River.

这些工程是："三北"（东北西部、华北北部、西北地区）防护林体系工程、长江中上游防护林体系工程、沿海防护林体系工程、平原农田防护林体系工程、太行山绿化工程、防治沙漠化工程、淮河太湖流域综合治理防护林体系工程、珠江流域综合治理防护林体系工程、辽河流域综合治理防护林体系工程、黄河中游防护林体系工程。

这十大林业生态工程是："三北"(东北西部、华北北部、西北地区)防护林体系工程、长江中上游防护林体系工程、沿海防护林体系工程、平原农田防护林体系工程、太行山绿化工程、防治沙漠化工程、淮河太湖流域综合治理防护林体系工程、珠江流域综合治理防护林体系工程、辽河流域综合治理防护林体系工程、黄河中游防护林体系工程，规划造林总面积1.2亿公顷。

Its perfect adaptation to the aridity of that area makes itthe last green curtain against desertion.

这种树能适应该区域的干燥气候，是抵制沙漠化的最后一道绿色屏障。

Aridness and trans-desert are two connected worldwide problems. It is also the most frequent or influential calamity on agriculture and animal husbandry in Inner Mongolia.

干旱及沙漠化是两个相互联系而又突出的世界性问题，干旱是内蒙古自治区发生最为频繁，对农牧业生产影响最大的气象灾害。

Its research areas Include: Climatology and biometeorology; Rainfall and its biological effects; Erosion and the deposition of sediments: dust storms; Dunes, their structure and formation; Microclimatology; Dew and hygroscopic moisture; Soil flora and fauna in arid lands; Seed germination and its improvement; Vegetational studies in desert regions worldwide; The physiology and ecology of plants and animals; Foraging patterns of mammals; Parasites and predators; Diurnal rhythmicity and phenology; The impact of grazing; Wildlife conservation; Anthropology and sociology of desert peoples; Oasis settlement; Human ecology and traditional land use; Land classification and improvement; Water control; Remote sensing; Desertification, its causes and control.

具体内容包罗万象：气候学和生物气象学；降雨和它的生物影响；沉积物的腐蚀和沉积；沙丘结构和形成；干旱地区的植物和动物群；寄生物和捕食动物；干旱地区的人类学和社会学；干旱地区的绿地建设；水控制和干旱地区的沙漠化的成因和控制等。

Today's earth faces many a problem of environm en t and ecosystem:"greenhouse effect",chemical pollution,acid rain,sand dust dev il,went short of water wealth,water and soil bereave,soil fallen into desert,spe cies eradication,forest demolish,etc.

今天的地球面临着许许多多的环境和生态问题，"温室效应"、化学品污染、酸雨、沙尘暴、淡水资源匮泛、水土流失、土地沙漠化、物种灭绝、森林破坏等等。

In fact there are many factors threaten the existence of human, such as: forest demolishment, soil deserted, the destroy of ozonosphere, the increasement of ultraviolet radiation; global wcermerth and the raise of sea level caused by carbon dioxide and so on.

事实上，森林毁坏，水土流失，土地沙漠化，臭氧层的破坏，二氧化碳等气体增多，酸雨蔓延，水生生态破坏，水污染和水枯竭，物种灭绝等等，使全人类面临来自海、陆、空全方位环境退化的威胁。

Problems in China's land ecology security in China involve soil erosion, soil pollution, soil desertification, salinization, alkalin-ization, soil depauperization, etc.

我国土地生态安全方面的主要问题有水土流失、土壤污染、土地沙漠化、盐碱化、潜育化、沼泽化、贫瘠化等，围绕这些土地生态问题，我国已经制订了《环境保护法》和《土地管理法》等综合性法律，又制订了有关的专项法规。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
