“…Thereinto, b j can be calculated as the Equation (10) (11) where, P can indicate the eigenvalue of ecological security level. Assumedly, if P∈ [2,3], the evaluation result is insecurity; if P∈ [3,5], the evaluation result is slight security; if P∈ [5,7], the evaluation result is critical security; if P∈ [7,8], the evaluation result is slight security; if P∈ [8,9], the evaluation result is security.…”

“…Qualitative research includes the concept of ecological security [2][3][4][5], the relationship between eco-security and state-security, and environmental indicator [6]. Xiao, et al [7] pointed out that previous research on ecological security highlighted the ecological health diagnosis, regional ecological risk analysis, landscape security and security management.…”

Currently, a series of ecological environmental problems have been brought about by high-intensity intervention of human beings, and ecological security is regarded as one of the most important national survival strategies. A methodology of urban eco-security evaluation has been introduced, including a conceptual framework of pressure-state-response (PSR) model, setting-up of the indicator system of urban eco-security evaluation (ISUESE) and empirical research. By virtue of the mean-deviation method, the weight coefficient of every indicator is confirmed. It has been found that the top three indicators are: per capita area of paved road, per capita area of cultivated land and green coverage rate of built-up area, which has a relatively prominent status in he urban ecological security. A calculation procedure of fuzzy comprehensive evaluation (FCE) method is applied in empirical research. The Mianyang statistical data during the period of 2005-2012 shows that eco-security keeps a favorable trend, but criticality security and slight insecurity are dominant. It has also been found that insecurity membership degree (MD) of environment pressure accounts for a very large proportion of total pressure. Membership degrees of criticality security and security in environment state are increasing gradually, and as far as environment response is concerned, security is significantly increased.

“…There is a wide variety of definitions about ecological security, which may focus on environmental security [19,20], multiple ecosystems including natural system, social system and economic system [21] ,and so on. By analyzing the listed definitions of ecological security, this paper concludes there are two significant elements of ecological security.…”

The focus of this study is to assess regional ecological security, based on a method of combining the ecological sensitivity evaluation and the ecosystem services evaluation of Tongling City, China. This approach may reduce the possible errors caused by basing the assessment on only one of these two evaluation methods. The PCA (Principal Component Analysis) and rectified ESV (Ecosystem Services Value) methods were employed in this study with the support of SPSS, RS and ARCGIS. The study showed the following results: the ecological sensitive area is mainly located among the wetland concentrated areas along the river in the north and the forested and green spaces within and around the city, and the area with the highest value is the mountainous areas in the south; the northern wetland area along the river and the southern forested mountain area have high ecosystem services value. Finally, the study identified the ecologically fragile and important services areas, and offered a reliable reference for Tongling's ecological protection and urban growth decisions by dividing the ecological security evaluation areas into areas with low, mid and high ecological security levels.

“…The US Central Combatant Command (US Military), whose are of responsibility includes Central Asia and portions of the Middle East, has recognized and endorsed this concept, making "environmental security" a key part of its engagement strategy 3 . Although there has been considerable debate as to whether environmental degradation or regional competition for scarce water resources can lead directly to violent conflict, there is general agreement that these factors exacerbate existing conflicts and can be regarded as a vehicle to stimulate broader regional cooperation [4][5][6] .…”
