Most of the precipitation intercepted in microbiotic crusts was dissipated through evaporation.

拦截在微生物结皮层的水分大部分以蒸发的形式损耗

There is a significant difference in daily change of soil moisture content at depth of 5 cm between the areas with and without microbiotic crusts.

因此，生物结皮被认为是荒漠地区土壤表面状况的指示物和荒

The increase of topsoil evaporation is due to that microbiotic crusts decreased soil surface reflectivity and enhanced the proportion of latent heat in net radiation.

地表蒸发量的增加是因为微生物结皮降低了地表反射率，并提高了蒸发潜热在净辐射中的比例。

As a result of its high capability in interception of precipitation and enhanced evaporation of soil surface, the development of microbiotic crusts will more and more threaten the soil water condition which the artificial sand-fixing vegetation should rely on.

微生物结皮的逐年发育使其对降水的拦截能力和地表的蒸发能力都逐渐提高，并改变了水分在土壤剖面中的分配过程和格局，这对人工固沙植被赖以生存的土壤水环境产生了越来越大的威胁。

There is a significant difference in daily change of soil moisture content at depth of 5 cm between the areas with and without microbiotic crusts.

结皮覆盖区与无结皮覆盖区土壤水分的日变化特征明显不同于距地表5cm处，而其他各土层的变化趋势则较为一致。

The contribution of soil microbiotic crusts to the diversity of insect species may be attributed to the facts that it stabilizes soil surface, improves soil environmental and there by provides suitable habitats and some food sources for the insects.

生物土壤结皮对荒漠昆虫多样性的贡献可能是由于稳定了土表、改善了植被系统中的土壤环境，为昆虫，特别是幼虫阶段提供相对适宜的土壤生境或部分食物来源。

Intercepted precipitation and enhanced evaporation by microbiotic crusts were the two main factors threatening the water reservoir in sand dunes.

微生物结皮拦截降雨和提高蒸发，是微生物结皮威胁沙丘土壤水库的两个重要因素。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
