人为干扰

Chongqing Municipality is in the west of China, semitropical range, the distribution of butterfly reflected the zoology- geography characteristic.

In addition, based on the analysis of the relationship among tidal flat structure, vegetable distribution and shorebird community, the result showed that tidal flat integrity, length of bulrush zone and algae saline zone, landscape diversity, human disturbance are the four key factors for shorebird to select habitats.

通过分析滩涂结构、植被分布与鸻形目鸟类群落之间的关系发现鸻形目鸟类对生境选择中，滩涂结构完整度、藨草带和光滩带的宽度、周边景观的多样性、人为干扰程度都是影响鸻形目鸟类栖息地选择的关键因子。

Undesirable structure and tree species simpleness etc are main problem in existing urban forest, influence urban forest effective exert its zoological function(2) urban forest landscape indexes show: urban forest fragment increased form 1985 to 1995, and decreased form 1995 to 2007, but as a whole, Beijing urban forest fragment is degressive, especially woodland and spinney land.

2在研究时段内北京市城市森林景观指数变化明显，从1985-1995年间破碎化程度增加，而1995-2007年间下降，1985-2007年总体呈下降趋势，其中有林地和灌木林两种主要城市森林用地类型的变化剧烈；城市森林尤其是有林地用地受到人为干扰影响强烈，斑块日益简单化，主要类型城市森林间相互转化现象严重，说明北京市城市森林在研究时段内发生了很大变化。

The ratios of the dry weight of stolon and ramet/the dry weight of genet in plot 1 and 5 are the highest, Dry weight of L.

结果表明，除人为干扰比较严重的生境外，基株大小与匍匐茎数量、单位长度匍匐茎干重之间存在极显著的正线形相关（P〈0.01），基株大小对分株的影响可能与匍匐茎数量有关；匍匐茎与分株总干重与基株干重的比值在海拔最高和最低两个样地中最大。

The article is primarily focused on the flora of subaerial algae of zonal vegetation in terrestrical ecosystem of NECT、subaerial algae's distribution regularity and the aspect both the natural and artificial disturbance which affect it's distribution.

本文着重研究了中国东北森林—草原样带中陆地生态系统中的各地带性植被内亚气生藻类的种类组成、亚气生藻类在各地带性植被内的分布规律及影响亚气生藻类分布的一些自然因素，同时也研究了某些人为干扰对亚气生藻类分布产生的影响。

Jiuduansha, the last virgin soil of Shanghai, suffers from nearly no jamming because the absence of development.

九段沙湿地是上海最后一片处女地，未经任何开发利用，人为干扰接近于零。

Animal's welfare can be feed back from their vocalism. We had some experiments to get 35 days old chicken's vocalization in different environment, including normal environment、 light off environment and people's disturbing environment. On the base of Mel Frequency Cepstral Coefficient, We introduction a new algorithm for feature extraction---Subband Mel Spectrum Centroid. We used support vector machine classification model to evaluate the performance of using different sound parameters.

本文通过研究35日龄海兰褐蛋鸡在正常状态、光照与人为干扰等应激下发声信息的变化特征，提出基于子带梅尔频谱质心的优化特征参数，并通过建立支持向量机模型，比较了采用优化特征参数与梅尔频标倒谱系数及其一阶、二阶导数组成的特征参数（MFCC_39）在识别不同应激中的应用效果。

Hierarchical cluster analysis suggests that higher avian diversity was expected in habitat with in large size woodlot, higher habitat diverse and less disturbance.

聚类结果表明，面积大、生境类型丰富及人为干扰相对较少的绿地，鸟类多样性高。

The result makes clear, in the belt of 22 rivers appearance that evaluates in place, be in natural, close nature, degrade the reach of condition of natural, artificialize occupies total river to grow respectively 4.5%, 18.2%, 68.2% suffer factitious interference on the whole with river of dwell of 9.1%; wild goose more serious, be in degrade natural state.

结果表明，在所评价的22个河样带中，处于自然、近自然、退化自然、人工化状态的河段分别占总河长的4.5%、18.2%、68.2%和9.1%；雁栖河总体上受人为干扰较严重，处于退化自然状态。

It was suggested that the microclimate's edge influence depth at the interface of farmland and forest ecotone in west Jilin varied with time and space, and depended on the vegetation's aspection at the two sides of the interface and the intensity of human disturbance.

说明在农林边界，小气候影响域存在着时空变化，其范围取决于边界两侧植被的季相变化和人为干扰的强度。

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。
