人为干扰

Flushing distances of Pluvialis dominica were less than those of Calidris temminckii under the condition of both one person walking and two persons walking, which indicated that Calidris temminckii was susceptive on human disturbance than Pluvjalis dominica, this was probably related with different foraging strategies of two species of birds.

这说明青脚鹬对人为干扰的反应比金斑鸻更为敏感，这可能与二者的觅食策略不同有关。

The objectives of the study were to: 1 reveal the responses of vegetation and soil to degradation by investigating community characteristics and soil physic-chemical properties; 2 quantify the contributions of human factors and natural factors and the relationship among the factors by analyzing the variation of each factor in past decades; 3 understand the succession of fenced undegraded meadow, artificial pasture, semi-artificial pasture and degraded meadow, and to 4 provide suggestions for restoration and rehabilitation of the degraded rangeland in the region.

本项研究旨在通过对黄河源区退化高寒草甸的植物群落特征和土壤特征调查，揭示植物和土壤养分对土地退化的响应；对源区人口及牲畜数量和国内生产总值，气候变化特点等因子的分析，量化人为干扰因子和自然因子的贡献率以及各因子之间的数量关系；以及对草地退化驱动力分析以及原生草地植被封育、人工草地、半人工草地的自然演替变化规律的研究，为高寒草甸退化草地恢复与重建提供科学依据。

The shallow sea will reach 2.49%, tidal-flat area 15.06%, and rivers 1.39%, reed 1.21%, reservoir pond 1.15%, shrimp field 11.68%, paddy field 36.44%, woodland 2.57%, construction land 15.59%, and unwetted land 12.42% by 2050, which indicates that the dominant factor is the human disturbance in Yalujiang River Delta.

这预示着人为干扰是鸭绿江口湿地景观变化的主导因素。

Chinensis was clumped, we found that trees were randomly distributed, especially the young life stages.

样方面积是50×100 m2。研究结果表明，和较少受人为干扰的种群相比，这一种群趋于随机分布，特别是小树和幼苗阶段的个体。

Different shrubberies have different effect on soil carbon management index.

结果表明，侵蚀环境下的坡耕地由于人为干扰，土壤碳库含量偏低，退耕营造柠条林可以显著增加土壤碳库各组分含量，并随恢复年限呈显著线性关系，25 a时TOC、LOC和NLOC分别较坡耕地增加271%、144%和204%，仅为侧柏林的32%、30%和29%，碳库指数和碳库管理指数较坡耕地明显增加，增幅分别达到144%和108%，仅为侧柏林的28%和43%；不同灌木林对土壤碳库管理的改善作用不同，恢复年限相同的沙棘林土壤碳库组分含量和管理指数明显高于柠条林，坡耕地营造灌木林后土壤经营和管理水平得到了显著改善，土壤系统向着良性方向转变。

Comparing the landscape types of 1995 with that of 2005, we find out that:①the natural arbors are decreasing, with patches more fragmentation, size more odds, shapes more complex;②the area of natural shrubberies is increasing, with patches less fragmentation, shapes more simple and formulary ,the size of patches more even;③the area of natural grasses is increasing, with patches less fragmentation, shapes of patches more odds;④the area of timbers is increasing, with patches more dominance in landscape, more connectivity;⑤the area of Eucalyptus increases, with patches less fragmentation, shapes of patches more complex , more convergence, more connectivity;⑥the area of orchards is increasing, more connectivity;⑦the patches of the rubber is becoming more assemble, more connectivity, more formulary;⑧the area of plowland increases;⑨the area of reservoirs, rivers and ponds increases, with patches more assemble;⑩the area of cities decreases, with patches more dispersing, with shape more complexthe area of countries increases, with patches less connectivity, more dispersing, with shape more complex; the patches of the rest lands are more dispersing, with shape more complex;(3)In the process of economic development in the upper reaches of the Changhuajiang river watershed, a series of the ecological environment problems have appeared because a lot of landscape function broke off, and the connection of human landscape with natural landscape decreased, which aroused by the fragmentation of natural and semi-nature landscapes increased, the stability of the landscape structure decreased, as well as stress of human disturbance, resource and environment upon the landscape increased gradually.

3昌化江上游流域在经济发展进程中，自然与半自然景观破碎度增加，自然景观结构稳定性下降，人为干扰、资源和环境对景观胁迫逐渐增大，中断了许多生态过程，导致城市等人文景观与自然景观连接度很差，产生了一系列的生态环境问题。

This paper deals with the characteristics of human -disturbed soils in Harbin city .

本文对哈尔滨城市绿地土壤的人为干扰类型特点进行了研究。

This is designed to eliminate the risk of any person interfering with the tenders submitted and therefore avoids corruption.

这样做是为了减少人为干扰提交标书的风险和避免受贿。

Research on epiphytes in forest canopies still is very active due to a lack of field data at the ecosystem level for a lot of forest types under different environmental conditions in many regions.

林冠附生植物的生长发育与分布格局除与宿主有关外，还受到环境因素（气候、地形、微生境条件等）和人为干扰的影响。

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.
