Abstract:

In this paper, we study the interactive relationship between the agglomeration of urban elements and the evolution of eco-environmental pressure. We build an index system for evaluating the agglomeration of urban elements and eco-environmental pressure. Using the entropy method and response intensity model, we analyze how urban elements agglomeration influenced eco-environmental pressure in Changchun from 1990 to 2012, eliciting the changing features and influential factors. Ultimately, we conclude there is a significant interactive relationship between the agglomeration of urban elements and the evolution of eco-environmental pressure in Changchun. This is inferred from the degree of this agglomeration in Changchun having increased since 1990, with the degree of eco-environmental pressure first decreasing and then increasing. Alongside this, the impact of urban elements agglomeration on eco-environmental pressure has changed from negative to positive. The main reasons behind this shift are arguably the rapid growth of urban investment and ongoing urbanization.

Key words: urban elements agglomeration, eco-environmental pressure, influential intensity, response index, Changchun, China
