“…Qi et al (2012), meanwhile, described the significant impacts of regional climate change, economic development, land use and constant increases in food production on arid regions in East Asia. Baolong Han et al analyzed the complex niches of large Chinese cities in the course of population concentration from the perspective of environmental niches, the social and eco-environment, and economic niches (Han et al, 2014), and carried out a quantitative evaluation of ecological security in the Beijing-Tianjin-Hebei region (Han et al, 2015a). Based on remote sensing data of land use and the normalized difference vegetation index, Cui et al (2015) constructed an environmental quality index to analyze the effect of Chinese urbanization over the previous ten years.…”

Global urbanization is exerting severe stress and having far-reaching impacts on the eco-environment, and yet there exists a complex non-linear coupling relationship between the two. Research on the interactive coupling effect between urbanization and the eco-environment will be a popular area of study and frontier in international earth system science and sustainability science in the next 10 years, while also being a high-priority research topic of particular interest to international organizations. This paper systematically collates and summarizes the international progress made in research on interactive coupling theory, coupling relationships, coupling mechanisms, coupling laws, coupling thresholds, coupling models and coupling optimization decision support systems. The research shows that urbanization and eco-environment interactive coupling theories include the Kuznets curve theory, telecoupling theory, planetary boundaries theory, footprint family theory and urban metabolism theory; most research on interactive coupling relationships is concerned with single-element coupling relationships, such as those between urbanization and water, land, atmosphere, climate change, ecosystems and biodiversity; the majority of research on interactive coupling mechanisms and laws focuses on five research paradigms, including coupled human and nature systems, complex social-ecological systems, urban ecosystems, social-economic-natural complex ecosystems, and urbanization development and eco-environment constraint ring; the majority of interactive coupling simulations use STIRPAT models, coupling degree models, multi-agent system models and big data urban computer models; and research has been carried out on urbanization and eco-environment coupling thresholds, coercing risk and optimal decision support systems. An objective evaluation of progress in international research on interactive coupling between urbanization and the eco-environment suggests that there are six main research focal points and six areas lacking research: a lot of research exists on macroscopic coupling effects, with little research on urban agglomeration and scale coupling effects; considerable research exists on sin-

“…The key issue in evaluating ecological security (ES) from the indicators was how to weigh each indicator with minimal subjectivity [51]. Claude Elwood Shannon put forward the concept of entropy and introduced information theory [59].…”

“…Claude Elwood Shannon put forward the concept of entropy and introduced information theory [59]. The entropy method is a mathematical method for calculating the index weight that is based on the comprehensive consideration of various factors that entropy information provides, and it has been widely used [28,51,60]. This approach assumes that the number of eco-security evaluation indexes of the evaluation object is m; they are XI (i = 1,2,3…,m) and we obtained the statistics for each indicator, assuming the matrix is R′ = (r ij ′) m×n (i = 1,2,…,m j = 1,2,…,n), defi ning r ij as the statistics of a certain index in a particular year.…”

At present, overseas and domestic eco-security early warning research is in the exploratory stage. This paper uses Kizilsu Kirghiz Autonomous Prefecture as the research object and constructs an evaluation index system based on the pressure-state-response (P-S-R) conceptual model. This study analyzes eco-security early warning in the study area using the granger causality test model, the entropy weight method, and the matter-element model, and analyzes the present eco-security situation and future development trends in the study area. The author hopes that this study can further enrich eco-security early warning research and provide a scientifi c reference for ecological security in the study area. The specifi c research results were as follows: 1) This article evaluated the plateau mountain ecological security early warning system, and the application of the Granger causality test was further implemented with targeted and objective index system selection, achieving a one-to-one analysis in the results and further enriching the research theory of the importance of eco-security early warning systems. 2) On the whole, the eco-security situation in the study area is gradually moving in a positive direction, but the low level of overall eco-security continues to cause great pressure. 3) From 2005 to 2014, the study area gradually attached greater importance to the construction of ecosecurity, but the overall eco-security level is low, and the overall eco-security regulation capacity is insuffi cient. 4) The key eco-security pressure in the study area mainly derives from industrial and agricultural development, although the control power is gradually increasing, but the control effect is not obvious, and the contradiction between ecological security and socio-economic development is still very obvious. 5) The study area is a typical earthquake-prone area, and fi nancial input into the governance of natural geological disasters due to the high frequency of earthquakes is gradually increasing; but the study area still needs to increase its investments.

“…So, the assessment of water environmental vulnerability is the process of multiple objective decision-makings, in which mathematics model needs to be established to provide scientific basis for the sustainable water environmental management. General assessment methods included fuzzy set theory, artificial neural network model, analytic hierarchy process and so on [2][3][4]. Those assessment methods have some difficulties for assessing complex uncertain water resources system vulnerability rationally.…”

Abstract-Rapid population growth and increased economic activity impose an urgent challenge on the sustainability of water environmental system in Beijing -Tianjin -Hebei (BTH) region. Water environmental system is a complex uncertain system under change which is of vulnerability. But water environmental system vulnerability research is relatively weak. In this study, we present a multifunctional hierarchy indicator system for the performance evaluation of water environmental vulnerability (WEV). This paper constructed the assessment index system of water environment system based on PSR model which contained 24 indicators considering social-economy conditions and situation of water resources. Weights were calculated by the method of analytic hierarchy process (AHP) and entropy, and fuzzy set pair analysis assessment method (FSPAAM) was applied to evaluate the degree of vulnerability in the Beijing -Tianjin -Hebei region.
