RETRACTED ARTICLE: Evaluation of human activity intensity in geological environment problems of Ji’nan City

Abstract

Human activity intensity evaluation is the basis of analyzing the impact of human activity on the region. With increasing scale and quantity of human activity, the impact on the ecological environment is also more and more serious. The multifactor evaluation model of human activity intensity is established by determining the classification standard index. Firstly, population density, gross domestic product (GDP) per capita, mining points, construction land ratio and land utilization ratio are selected as quantitative indexes. Secondly, the weights of evaluation indexes are obtained by using objective valuation method. Further work, the quantitative evaluation model and systematic analysis of human a`ctivity intensity for Ji'nan city are established by multifactor method. The results show that the areas with the highest intensity of human activities are mainly distributed in Ji'nan urban area, the areas with higher intensity are mainly distributed in some towns of Licheng District and the urban areas of counties and cities, the areas with middle intensity are mainly distributed in the areas near Ji'nan urban area and counties, and the areas with lower intensity are mainly distributed in some areas far away from counties and cities. Quantitative evaluation of human activity intensity is helpful to investigate the changes of ecological environment.

RETRACTED ARTICLE: Guest editorial of the special issue “remote sensing in water management and hydrology”

“…In simple terms, this work offers a dynamic theoretic model to study longitudinal-transverse coupled vibrations. In the article "Evaluation of Human Activity Intensity in Geological Environment Problems of Jinan City," the authors Kai Peng et al (2020), analyses human activity intensity through the determination of classical standard index. The weights of the evaluation index are attained using objective evaluation method.…”

Grazing intensity and human activity intensity data sets on the Qinghai‐Tibetan Plateau during 1990–2015

“…Population density and GDP density were important factors reflecting the interactions between human activity and ecosystems (Peng et al, 2020). Population data for 1990, 1995, 2000, 2005, 2010, and GDP density for 1995, 2000, 2005, 2010 and 2015, were obtained from the Resources and Environmental Data Cloud Platform, Chinese Academy of Sciences (http://www.resdc.cn/).…”

Human Activity Intensity in China under Multi-Factor Interactions: Spatiotemporal Characteristics and Influencing Factors

“…As population size is the main body of HAI [36], population density is selected as an influencing factor of HAI.…”

“…We comprehensively evaluated HAI in China from 1980 to 2018. Unlike existing studies [32][33][34][35][36][37][38][39][40][41][42][43][44], this paper comprehensively considers multiple dimensions of HAI changes and reveals the spatial heterogeneity of such changes. Although the HAI in the Yangtze River Delta in 2018 was slightly lower than that of the Beijing-Tianjin-Hebei region, its growth trend in the Yangtze River Delta was steeper.…”
