The results indicated that organic fertilizer at a rate of 75000 kg/ha or organic fertilizer (75000 kg/ha) with compound fertilizer at a rate of 300 kg/ha had higher effects on genetic diversity of soil microbial community under field conditions. Treatment of fertilizers as base application at level of 600 kg/ha resulted in decrease of DNA sequence richness index and diversity index of soil microbial communities, and the similarity coefficient of DNA sequence from soil microbial communities was the lowest compared with control. Organic fertilizer treatment was conducive to increasing DNA sequence diversity index and evenness index of soil microbial communities.

结果表明，在本试验条件下，基肥为75000kg/hm^2有机肥处理和75000kg/hm^2有机肥加300kg/hm^2复合肥处理最好；基肥为600kg/hm^2复合肥处理使土壤微生物群落DNA序列丰富度指数和多样性指数显著下降，与对照的DNA序列相似系数最低；有机肥处理有利于土壤微生物群落DNA序列多样性、均匀度和黄瓜产量的提高。

Among 150 species, 32 were adapted to urbanization, 77 adapted slightly to urbanization, 41 were sensitive to urbanization; 37 were interior species, 91 edge species, and 22 insensitive to edge; 93 distributed in only one kind of habitat, 34 in two, 4 in three, and 19 in four.

城市边界对西部山区鸟类群落的影响是双重的，一方面为某些鸟类提供了可利用的资源，另一方面干扰等因素降低了边界区鸟类的多样性，消解了西部山区鸟类群落分布的边缘效应格局。在总体上后者的影响大于前者。

在群落交会带中，单位面积内的生物种类与族群密度比其相邻群落高

This regional community structure is simple. The shrub layer and the liana layer are undeveloped. The syngenesis time is short.

调查表明该区域群落结构简单，灌木层和层间结构不发达，群落演替时间短。

Through analyzing the life-form, it could be seen that phanerophyte species were absolutely dominant in the communites.

对江西吉安退化湿地松群落外貌特征进行分析，结果表明：该区湿地松群落中，以落叶灌木居多。

Results show that phanerophytes is the dominant life form in the three forests, in which micro-phanerophytes is in the largest proportion, and then followed by hemicryptophytes. In the three communities, the principal leaf size is mesophyl1, the main light eco-form is heliophyle, and the dominating water eco-form is mesophyte.

结果发现，3个群落都以高位芽植物为主，其次为地面芽植物；在高位芽植物中又都以小高位芽植物比例较高；3个群落的叶型谱以小型叶为主，光照生态类型谱以阳生种类为主，水分生态类型谱以中生种类占优势。

According to the results of correlation analysis and the results of former research, the metal ions were thought to have little influence on the microfauna community in the two sewage treatment plants.

结合前人研究结果以及本研究所做的微型动物群落与重金属离子浓度的相关分析，可以认为重金属离子对两个污水处理厂活性污泥系统中微型动物群落影响不大。

However, few studies have been conducted on the mechanism of altitudinal species diversity patterns in the montane forest communities.

研究深度也从根据样地资料的简单描述和分析，发展为山地森林群落物种多样性机理假说的提出与证实，尚未见有关山地森林群落物种多样性垂直格局机理的报道。
