According to the distribution of species and amount, the author makes a PCA analysis to the different habitats. The analysis of hierarchical cluster to different habitat is according to the distribution of species. According to the results of the two ways of analysis and the factual condition of environment, the environment of Daqinggou is divided into 3 types of habitat that are described as the hygric plant community in the bottom of ditch, xerophytic plant community in the top of ditch and single type plant community.

以直翅目昆虫种类和数量的分布为属性对不同生境作PCA分析并以直翅目昆虫种类分布为属性作等级聚类分析，两种分析方法所得结果十分相似，结合分析结果和实际情况将大青沟7种不同生境分为3类，分别命名为沟底湿生植物群落，包括水曲柳植物群落、湖边湿地植物群落和稻田植物群落；沟上干早植物群落，包括沙丘草地和大果榆植物群落；单一型植物群落，包括人工针叶林植物群落和蒙古栋植物群落。

In addition, baculovirus are noninfectious to vertebrates, and their promoters have been shown to be inactive in mammalian cells. Futhermore, the expression level of some recombinant proteins is up to 1000 mg/L. Finally, recombinant proteins are soluble and antigenically, immunogenically and functionally similar to their authentic counterparts. In this article, we used the transfer vector pBlueBac of AcNPV (Autographa californica Nuclear Polyhedrosis Virus) to construct the recombinant baculovirus AcNPV-GM-CSF by in vivo recombinantion.

本文中，我们首先利用苜蓿夜蛾核型多角体病毒带β-Galactosidase 基因标记的非融合蛋白基因转移载体pBlueBac，通过细胞内同源重组的方式将hGM-CSF基因成功地插入病毒AcNPV的基因组中。hGM-CSF基因编码信号肽和完整的氨基酸序列。hGM-CSF基因在感染重组病毒的草地夜蛾培养细胞Sf9中得到表达，感染后的Sf9细胞培养液能刺激人骨髓细胞在体外形成典型的集落，表达水平可达2.7〓CFU／ml。

Before the meadow of sunshine of Tsinghua university early morning, the jeans is recreational impersonative Matt accepts sina science and technology brief special report, develop the current situation with respect to WordPress, do poineering work wait for a topic to make communication.

在清华大学清晨阳光的草地前，牛仔裤休闲装扮的马特接受新浪科技简短专访，就WordPress发展现状、创业等话题做出交流。

From 1985 to 2000, woodland, grassland, industrial and residential land tended to be more inerratic and stable, whereas cropland and water area more complex and unstable. Unused land remained unchanged. During this period, the land use structure of Suzhou was unsteady, and its form became more complex.

从1985年至2000年，林地、草地以及居住与工矿用地趋于规则、稳定；耕地、水域用地趋于复杂、不稳定；未利用土地没有变化；苏州市土地利用结构不够稳定，土地利用形态趋于复杂化。

Land cover of Shanxi Province had been monitored from 1980s to 2005.Based on remote sensing and GIS technique, analysis on spatial\|temporal characteristics of land cover change and driving factors was implemented.Results show that:(1)Changing area: Area of industrial and transportation land、rural settlement and a spot of grass land is increasing, on the other side, area of dry land, irrigable land, a spot forest land and bottom land etc is decreasing.

以遥感与GIS为技术支撑，对山西省20世纪80年代到2005年的土地覆盖进行了动态监测，并分析了土地覆盖的变化特征及其驱动因子；监测表明，山西省土地覆盖时空变化特征：(1)变化数量：城镇建设用地和农村聚落面积增加显著，草地有所增加；旱地和水浇地减少明显，森林和河湖滩地略有减少。

The yield of biomass of the ground part of Juncus Effuses growing on the soil polluted by wastewater or tailings of Lead/Zinc mining decareasd by 28.23% or 37.1% respectively, but the activities of POD, SOD and CAT were all higher than those in CK.

生长在矿毒水和铅锌尾矿污染土壤中的灯心草地上部生物量分别下降28.23%和37.1%，但POD、SOD和CAT 3种酶活性均高于对照。

After a two-year observation, it was found that Pangola grass is not suited to grow in lateritic soil of the mountainous slop land, and considered to be the good forage crop under the present condition of Taiwan.

因此不但可以节省种植当年的除草需费而且可使原野地真正变成良好的牧草地。 4。盘固草为无性繁殖，种苗取生长期间45~60天而且较为粗壮的匍匐茎，行距50公分，株距20~30公分，每穴种1~2支苗。

PartⅣStudy on the chemical constituents of Ligularia atroviolaceaLigularia species is a perennial herb from Compositae,and mainly distributed in damp,shaded areas of western China,especially the provinces of Gansu, Sichuan and Yunnan.

第四部分黑紫橐吾化学成分研究黑紫橐吾Ligularia atroviolacea为菊科千里光族橐吾属多年生草本植物，生长于海拔3000-4000米的高山草地之中，广泛分布于我国云南西北部、四川、贵州、湖北西部和甘肃西南部等地。

Most species' populations were decline in last fifty years, especially since the last 1980's, the populations such as Alpine Musk Deer, Przewalski's Gazelle and Red Deer etc. declined dramatically;(5) Desertification and grassland degredation are obviously affected by climate change on macrographic scale, anthropogenic activities is an important driving role for desertification, herbing, land-development and urbanization have majority impact to biodiversity spatial pattern and its loss.

祁连山区动物资源组成成分复杂，总体上缺乏自身特有的种类，哺乳动物区系特点不很突出，既包含了东部黄土高原和东南湿润地区的兽类成分，又不乏青藏高原特有种类，同时还与新疆的动物区系有一定的联系，近50年来尤其自上个世纪80年代以来，多数种类的种群数量呈下降趋势，其中以马麝、普氏原羚、马鹿等物种的数量下降的最为显著；（5）土地沙漠化和草地退化在宏观尺度上受气候因素影响较大，人类活动对荒漠化的加速发展起着重要的驱动作用，尤其是放牧、土地开发和城镇化建设对生物多样性资源减少以及空间分布格局影响较大。

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。
