Based On Space Method For Human Factors On The Ecological Environment Effect Of Liaohe River Basin(Liaoning Coastal City) As An Example

Regional ecological environment changing is mainly affected by natural factors and human factors,and with the rise of human civilizations,especially since the industrial revolution,human factors influence on ecological environment plays an increasingly important role.The rivers that gave birth to civilization since ancient times is one of the most strongly affected by human activities,urban ecological environment along the river carries a large population not only basic life,also bear the pressures of economic growth.Liaohe River is one of the seven major rivers in China,during the agricultural civilization as early as 5,000 or 6,000 years ago,Hongshan culture brewed in Liaohe River,after the founding of new China,the northeast area has become China’s important industrial base.A lot of frequent human activities to some degree damage the ecological environment in the Liaohe River basin,especially in the the northeast area and then round the revitalization process,study the impact of cultural factors on the ecological environment is necessary.Based on the quantitative evaluation method of ecological carrying capacity-Space method and then construct a model of the influence of human factors on the ecological environment,and according to model human compute human factors impact on the ecological environment,compared with the critical value,to judge the impact of human factors on the ecological environment in this area is modest,equal or exceeding.According to the human factors for basin ecological environmental impact,using Mapinfo software makes a difference during the corresponding thematic map.Read view much of the system,consulting experts on the basis of adjusting measures to local conditions to establish evaluation index system of ecological environment in the region,and based on the variation coefficient method to determine the weight of each index in different years.The time scale for the 2005-2015 a total of 11 years of research,study the spatial scale of Liaohe River basin along the 14 cities in Liaoning including:Changtu Country,Kaiyuan City,Tieling Downtown area,Tieling Country,Diaobingshan City,Kangping Country,Faku Country,Xinmin City,Shenyang Downtown area,Liaozhong Country,Taian Country,Panjin Downtown area,Panshan Country,Dawa Country.The results show that: From the perspective of time,cities within the basin as a whole,human factors on the ecological environmental impact over the years are over;every year human factors for basin ecologic environmental impact index of less stable,the trend is basically the same,only 2005 larger changes in human factors for basin ecologic environmental impact;The year 2009 as good ecological environment over the years,human factors,excessive number of cities at least,and the year 2007 with poor ecological environment over the years,human influence over most of the city.From the perspective of space,Changtu Country,Dawa Country,Panshan Country human factors on the ecological environmental impact over the years is exceeding,but Diaobingshan City,Liaozhong Country human factors on the ecological environmental impact were modest over the years,other cities’ human effects of different factors on the ecological environmental impact different years.Paper results can provide reference for Liaohe River along the city’s ecological environment and sustainable development.
