The background survey and tracking survey of artificial reef area in Chenghai Laiwu were carried out before and after reefing in 2003 and 2007, respectively. The results indicated that after the deployment of artificial reefs, the biomass density of fishery resources increased by 25.63 times, which were much higher than before. The resources species was much more abundant; total number increased from 23 to 41, which increased by 0.78 times. The crab resources sharply increased by 1.75 times after artificial reef were deployed. Harpodon nehereus and Portunus sanguinolentus , which did not appeared in background survey, now became the dominant species in tracking survey. There were high diversity indexes in artificial reefs area and control area in tracking survey. In conclusion, the results indicated that the fish-aggregating effect of artificial reef site has improved a lot, and the community structure and the habitat environment have been significantly improved.

摘 要：2003和2007年分别对澄海莱芜人工鱼礁区进行了投礁前的本底调查和投礁后的跟踪调查，结果表明，投礁后礁区海域游泳生物的资源密度明显比投礁前高，增加了25.63倍；礁区海域各类资源种类均比投礁前丰富，总种数由投礁前的23种增加至41种，比投礁前增加了0.78倍，其中，蟹类种数增加最多，增加了1.75倍；在本底调查中没有出现的经济种类龙头鱼 Harpodon nehereus 和红星梭子蟹 Portunus sanguinolentus 在跟踪调查中已成为主要优势种；Shannon-Wienver多样性指数在礁区和对比区均比投礁前有所增加。

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 safety of the Prescription was comfirmed by 〓Ca determination of transmembrane inflow. The tablet procedure was studied in such aspects, i. e. compressing method, the category and ammount of HPMC, binder and malactic with monofactorial test. Then Compound Danshen Sustained-release Tablet was made, which can release composition 12 hours continuously.

在缓释剂型研究实验中，采用钙拮抗作用确定了有效部位配比处方安全有效，采用丹参素和原儿茶醛的体外释放度作为评价指标，运用单因素方法筛选确定了亲水凝胶骨架片的压片方法、凝胶骨架材料种类与用量、粘合剂的种类、润滑剂的种类，优化形成了复方丹参缓释制剂处方，制成了l天2片缓释12h的复方丹参缓释片。

The majority of the insects feeding on or parasitizing in Picea crassifolia were monophagous or oligophagous; the minority of them were polyphagous.

There are 18 species of Paphiopedilum in China. Most of them grow in limestone regions and are epiphytic or terrestrial. There are two types of leaves mottled leaves and green leaves. They distribute in subtropics of China. Five species of subgenus Brachypelalum are the most primitive grou p of Paphiopedilum in China and four of them distributed in the limeston e re gions of Eastsouth Yunnan. Most species of Paphiopedilum distribute in this area,too.

The species of Sphingidae (Lepidoptera: Sphingidae ) in garden plants in Guangzhou and their hosts;2. Based on the study of species and hostplants of Sphingidae in Beijing,It is reported that there are 24 genus,38 species of SPhingidae distributing in this area,and indicates the existence of Langia zenzeroides szechuana in Beijing at the first time.

通过对北京地区天蛾的种类、数量及寄主植物的调查，首次报道北京地区共有天蛾24属38种及亚种，并且首次报道了川锯翅天蛾等种类在北京地区的分布，经调查，北京地区天蛾的寄主植物有27科，通过食性分析发现多食性种类占大多数。

The investigations found that there were obviously different in the species richness and individual abundance in the different sampling site. The number of species and the quantity of individual collected from the littoral zone were much higher than those from the open area. The protozoan colonizing rate on PFU in the littoral zone was also significantly higher than that in the open water.

研究结果表明：（1）湖中敞水区和沿岸带原生动物种类数和个体丰度存在较明显差异，前者低于后者；（2）同一生境条件下PFU人工基质收集的原生动物种类多于采自自然基质的种类；（3）定量数据显示该湖原生动物个体数量秋、冬季在每升水中440—180个个体之间波动，较少的个体丰度与该湖属寡营养型特征有关。
