Using arid area (annual rainfall about 200mm) and dankness area (annual rainfall about 600mm) contrast test, determining the new potato variety's drought resistance, chlorophyll A, B content and CAT activity in the different growth period, study the relation between chlorophyll content, CAT activity and the drought resistance.

采用干旱地区（年降雨量200 mm左右）与阴湿地区（年降雨量600 mm左右）对比试验，测定马铃薯品种生育期的叶绿素a、b含量和CAT活性，研究其与抗旱性关系。

Durum wheat is tetrapolid (28 chromosomes) and contains two basic genomes, whereas common bread wheat (Triticum spp.) is hexaploid and contains three basic gonomes. Durum is best adapted to growing in arid regions of the world: Italy and other areas in Southern Europe; Turkey and Syria in the Near East; Morocco and Algeria in Africa; Soviet Union; and Canada and Northern United States in North America.

多伦小麦产品是四倍体(28个染色体)并包含两个基本基因组，而普通的面包粉是六倍体并包含三个基本基因组，多伦小麦可以很好的适应生长于世界上的干旱地区环境，例如：意大利和南欧一些地区；近东的土耳其和叙利亚；非洲的摩洛哥和阿尔及利亚；前苏联；以及北美洲的加拿大和美国北部。

The landform of this area is a thpyical erosional and depositional topography of semiarid one.

这个地区是一种典型的半干旱地区的腐蚀和沉积地形。

The GPI method assumes that the cloud with brightness temperature below 235K would be rainy, then the area of rain is equal to the coverage of cold cloud below 235K. It may be suitable for most part of China at tropic and subtropic area. But for northern part and plateau area of China, the GPI overestimates precipitation due to lack of enough water vapor.

4GPI方法假定云顶亮温低于235K时，将产生降水，降水区的面积就等于低于235K亮温覆盖的区域，这在热带和中纬度大部分地区可能是适用的，但对我国北方干旱地区以及高原地区，则存在明显的高估，表明有云不一定会有雨，为了修正西北部降水的系统性高估，引入相对湿度修正因子，即在一定温度条件下，加上一定的湿度条件，才能形成降水。

These bryophytes, in this sense, have to tolerate great heat and drought.

在干旱和半干旱地区，影响苔藓植物分布的环境因子包括降水、p H值、Ca CO3 含量、植被盖度、有机质含量以及土壤质地等，其中起重要作用的是降水。

Rainwater catchments system engineering is an important way to develop agriculture, reduce erosion of soil, improve environment and increase incoming of farmers.

雨水集蓄利用工程是干旱半干旱地区发展农业生产、减少水土流失、改善生态环境、提高农民收入的重要途径。

This paper reviews the predictions and management implications of two current paradigms in the ecology and management of arid and semi-arid rangelands.

该文对当前干旱和半干旱地区的生态和管理的两个模式做了综述。

Suiting for disposing in factory and suburb outer edge belts in terms of protection against wind and preventing sand from drifting, the tree is populous, and the bashes are sand willow and slender branch sweet vetch Among them, sand willow shrub forest in the nearly stratum 10cm layer, can decrease wind speed by 60.3%.

上述野 外试验和盆栽试验都证明上、下覆膜和美国干水处理保墒效果较好、性能稳定，可以在干旱半干旱地区城市森林植被建植过程中大面积推广应用。

Dry land water Kiln is the kind of micro-catchment and conservancy project to retain water from running off and make full use of the natural precipitation so as to meet the needs of humanbeings, animals and crop production in dry and semi-dry land areas.

旱地水窑是干旱半干旱地区拦蓄地表径流，充分利用自然降雨以满足人畜生活用水和生产用水的一种微集水保水工程。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
