人为干扰

• The results indicated that hydraulic power station , residential area , and road are three primary human impact sources , and the distance of significant impact on landscape structure of around area for these sources is between 10001200m . this distance can be used to divide the whole study area into natural landscape and human impact landscape suitably . human landscape distribution to land form resulted that the area with elevation from 2400 to 4800m and slope gradient from 20 to 40 are the heaviest human impacted region in wolong natural reserve
  结果表明，工作区内水电站居民点和道路3种不同人为影响发生源对于周围景观结构的显著影响距离为1000 m ，利用这一距离可以对工作区的自然景观和人为影响景观进行合理分割海拔2400 m和坡度20区间为卧自然保护区人为干扰活动强度最大的区域，这种人为影响景观的空间分布特征对于保护区的自然管理工作威胁极大。

• The area in question has great conservation value as following aspects : the population of butterfly shows great species abundance ; the heterogeneity of habitat revealed by the presence of multi - subspecies and multi - morphological species provides animals a steady habitat ; the faunal character and vertical distribution of butterflies show great value of ecological study ; the mid - mountain 8002600 ? m that has better environmental condition and less human disturbance is a typical
  秦岭对东洋种的阻隔作用大于对古北种的作用。中山地带8002600m即暖温带落叶阔叶林和中山针阔叶混交林带环境状况良好，气候条件优越，受人为干扰少，因而物种丰富多样性较大。研究地区具有很高的保护价值。
• Based on literature and the data of desert survey , the paper introduces the status quo and direction of china ' s desertification , discusses the key reasons caused desertification by changes in climate and irrational activities of man , holding that once man ' s interference is controlled and protective measures are taken , land under desertification in semi - drought areas will soon recover to arable land naturally
  摘要该文根据有关文献和资料，介绍了我国沙漠化的现状及发展趋势，论述了气候变化和人类不合理活动是造成沙漠化的重要原因，认为只要控制人为干扰，并采取防治措施，半乾旱地区的沙化土地很快就能自我恢复。
• From the results , we can conclude that the vegetation landscape in the core area can provide a quite appropriate living environment for crossoptilon mantchuricum , but the rather big difference between the areas of each landscape element , the quite low diversity , the rather high degree of dominance as well as the influence of human activities are all the problems to be solved in the future management of the natural reserve
  分维数表明，森林景观受人为干扰较大，说明旅游给核心区内的森林景观造成了一定的影响。从以上结果可以看出，核心区内的植被景观可以为褐马鸡提供较为适宜的生存环境，但各景观要素之间面积差异较大、多样性较低、优势度较高以及人为活动造成的影响等都是保护区今后工作中需要解决好的问题。
• First , according to the heterogeneity of landscape in zherong , the author selected the dominant elements such as topography , altitude and climate which reflect the large scale of area differences and the stastistical materials which have long - reaching effects on the county . the county was divided into 8 landscape types : resident and trade area , industry area , traffic land , farmland , garden and greening land , water area , forestry area , unclaimed land . the types have 21 subtypes , the city area , county area , heavily polluted industry area , little maching area , road land , country road land , cultivated land . mushroom land . taizishen land , tea land , man - made greening land , garden land , reservoir area , river and creek area . defending forestry area , forbid - cut forestry area , bamboo area , economical forestry area , unclaimed mountain , unclaimed land , unclaimed water
  同时，根据该县景观异质性强的特点，以行政区划单位、人为干扰强度、景观要素和功能流为柘荣县城市景观分类的原则和依据，选择地貌、海拔、气候等反映区域分异的主导因子和对该县社会经济影响深远的统计资料，将全县划分为8个景观类型，即居住区和商业区景观、工业区景观、交通用地景观、农田景观、公园绿地景观、水体景观、林区景观、未开发地景观。景观类型下又划分21景观亚类型，分别为城区景观、村落聚居地景观、重污染工业景观、小加工业景观、公路景观、乡村道路景观、耕地景观、食用菌景观、太子参景观、茶园景观、人造绿地景观、公园景观、水库景观、溪河景观、防护林景观、封山育林区景观、竹林景观、经济林景观、荒山景观、荒水景观、荒地景观等景观亚类型。
• In original and jamming slightly vegetation , because dead roots , branch and leaves back to soil , soil organic matter higher , soil available phosphorus higher , too ; chemical and physical characters of soil were stabilization . the reason were original vegetation have more species and structure of community was stable . the degradation of fertility and structure of soil in secondary vegetation was influenced by change with structure and form of community
  在人为干扰小的原生性森林，植物种类丰富，群落结构稳定，植物死根系和枯枝落叶全部回归土壤，土壤有机质含量高，养分呈有机态为多，故有效磷较高，土壤理化性质较稳定；次生植被群落土壤结构和肥力的退化是由于群落组成和结构的改变导致枯枝落叶成分和土壤发规白山地还小问沙消民俗一非定俗地征王卿乔忡旺w比收财育环境差异而引起，次生植被土壤的退化状态随植被退化程度不同而有差异。
• Except for the description for behavior , this paper also discussed the mechanism of behaviors . biological factors affecting alligators ’ behaviors were described , including age , food resources , human impacts . non - biological factors were demonstrated also in the study , such as space , temperature and living habitats
  在行为描述的基础上，对扬子鳄的有关行为机制进行了探讨，而影响扬子鳄行为表达的生物因素主要包括年龄、食物资源和人为干扰；非生物因素主要包括空间、温度和生境等。
• Diversity index of tree layer decrease with the increase of mankind disturbance , however , the diversity index of fuxingshi is less than comparison plot , it is likely that there are some history reasons , or the quantities of potential settlers are less , and it is far from species source plot or there are some interactions between these species in the communities
  乔木的多样性指数随人为干扰的增加而降低，但复兴寺多样性指数比对照样地小。幼树和灌木的多样性指数随干扰加剧和片断化隔离时间的增加而呈降低趋势。草本植物的多样性指数在复兴寺、聚云峰和猿啸峰较连续森林高，在其它片断森林则较低。
