人为干扰

By demonstration analysis, EPS and ROE from 2002 and 2005 which are all from 54 agricultural listed companies dont obey the normal distribution, thereby they are both likely to be interfered factitiously.

通过实证分析，54家农业上市公司2002年到2005年的每股收益与净资产收益率都不服从正态分布，两项指标有人为干扰的可能。

To understand the mechanisms of how plants affect soil biota from a plant physiological perspective, litter exclusion, girdling and root trenching experiments were carried out to investigate the impacts of above/belowground resource inputs on soil nematode communities.

本论文研究了云南哀牢山人为干扰条件下和植物群落自然演替过程中植物群落变化对土壤线虫群落的影响，并通过去凋、环割和切根三种方法分别控制植物的地上地下资源输入，从植物生理机制的角度分析植物对土壤线虫群落的影响机制。

In the landscape design of experimental village, based on investigating of environment character and analyzing of actuality, through protecting cordillera, water system and vegetation, restoring regional biogeocenose and reducing jamming, safeguard healthy of soil process, through constructing public stage, reforming courtyard and street space, improved living circumstance quality, through assimilating ancestor survival experience, developing tradition, and using local materials built endemic landscape and helped indigene identify with their homestead.

在试点村屯环境景观设计中，重视村屯环境景观特征，针对存在的问题，保护山脉水系和植被、修复被破坏的乡土生境、降低人为干扰以维系生态过程健康，构建公共活动场所、重组院落和街巷空间以改善生活环境质量，汲取先民生存经验、发扬优良传统、就地取材营建乡土景观以帮助当地人重新认同生活的家园。

Since the species quantity at the shrub, herb and liane in D is more than that in C, The Shannon-Wiener index and the species' evenness showed that human-caused disturbance affected much more to the species at upper communities and the tall trees were not recovered entirely in D.

群落各层次的Shannon-Wiener指数及其均匀度计算表明，人为干扰对群落上层物种多样性影响较大，D群落高大乔木待恢复。D群落经过多年封山育林，由于种类入侵和竞争，正在形成物种更为丰富的当地典型地带性植被类型。

Functional requirements of habitat for these two species, expressed as habitat suitability and marginal density efficiency, and factors reflecting human disturbances such as the weighted road density and buildup density, were used in the calculation of a cost surface for Least Cost Analysis.

因此挑选杂食性的台湾黑熊及草食性的台湾长鬃山羊为目标物种，利用物种对於两个栖地因子（栖地适宜度、边际密度效应）及人为干扰因子（道路加权密度、建物密度）的反应强弱，制作成本曲面图。

The human disturbance with different strength and the different vegetation type also influenced the number and distribution of carbon and nitrogen cycle genes.

不同强度的人为干扰和不同的植被类型，对土壤微生物碳氮循环基因种类与分布有显著差异。

Constructed wetlands include canal, pond, fishing pond and paddyfield. Types of wetlands in Sanchahe area are typical and representative. The wetlands area is suitable. Water quality is perfect.

湿地的类型具有典型性和代表性，湿地的面积适中，水质良好，但水资源季节分配不均，人为干扰严重等问题是湿地保护的制约因素。3。

In July 6-12, 1982, the population numbers and summer habitat of the Mongolian wild ass Equus hemionus kemionus Pallas were studied by aerial census ing in the Kalamaili Mountains Wildlife Reserve situated in the northeastern part of the Xinjiang Uygur Autonomous Eegion.358 wild asses (0.02 per square km on average) were found by the method of total area census based on the parallel strip transects for conducting aerial census , lasted 32 hours and 21 minutes flying hours These animals separ...

1982年7月航空调查了卡拉麦里山有蹄类野生动物保护区内野驴Equus hemionus hemionus Pallas的夏季栖息地及种群数量。见野驴358头，平均密度为每平方公里0.02头，多集中栖居在保护区的东北部。初步分析影响野驴夏季栖息地的因素是水、地形及人为干扰。

The analysis results indicated that the cause of wild animals was the population rampancy, species extinguishment, ecosystem decline and so on, but human disturbances were the original causes.

分析表明，兽害的成因有种群爆发、物种灭绝和生态系统衰败诸多因素，而人为干扰是各种现象的起因。

The results showed that grassland and farmland were the main land use types of research area with obvious reciprocal transformation. Grassland was mainly transferred to farmland in 1975-1990. Farmland was chiefly converted to grassland, and grassland tended to increase in 1990-2004. The landscape diversity in the study area rose with the contagion index decreasing and fragmentation degree being intensified during 1975-2000. The advantageous patches maintained good connectivity with the increasing patch cohesion index and the decreasing landscape fragmentation during 2000-2004. The change of human interference intensity played an important role on the variation of land use structure. Land use intensity was mainly affected by the changes in population as well as national land use policies. In the following 20 years, the agriculture land area would tend to decrease, the grassland and unused land area would have a slight reduction by contrasting the increasing the forest land area notably.

结果表明，近30 a来，草地和农业用地面积在该研究区占居主导地位，并且它们之间发生着明显的相互转化。1975－1990年，草地主要向农业用地转移，1990－2004年农业用地主要转化为草地，草地面积增加；1975－2000年，研究区景观多样性升高，蔓延度指数下降，破碎化程度加剧；2000－2004年景观内优势斑块具有了很好的连接性，聚集度增大，整体景观格局破碎化程度降低；人为干扰强度的变化对土地利用结构的变化具有重要作用，土地利用强度主要受人口数量以及国家土地利用政策的影响；在未来20 a间农业用地面积会继续减小，草地、未利用土地面积将有小幅度降低，林地面积会显著增加。

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。
