![]() The purpose of this paper is to present a theoretical and methodological framework for urban eco-security evaluation by developing a multilayer, multicriteria indicator system based on the PSR model, which enables decision makers to understand the dynamics changes of urban eco-system under the human intervention and make scientifically-based and effective decisions on Mianyang city’s sustainable development. In general, there is no universally accepted definition of ecological security, its parameters, and appropriate research methods, and also there has been no unified and well-recognized indicator system. Evaluation methods, such as a mathematical model, ecological model, landscape ecological model and digital terrain model, are employed for the assessment of eco-security, but all have pros and cons. Moreover, eco-security evaluation has close connections with ecosystem health evaluation, ecological risk evaluation, ecosystem service evaluation and ecological carrying capacity, and these ideas inform our work about the indicator of eco-security evaluation pattern, and ecological security monitoring and prediction. pointed out that previous research on ecological security highlighted the ecological health diagnosis, regional ecological risk analysis, landscape security and security management. Qualitative research includes the concept of ecological security, the relationship between eco-security and state-security, and environmental indicator. There exists qualitative and quantitative studies in the literature about ecological security. 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. It has also been found that insecurity membership degree (MD) of environment pressure accounts for a very large proportion of total pressure. 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. ![]() A calculation procedure of fuzzy comprehensive evaluation (FCE) method is applied in empirical research. 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. By virtue of the mean-deviation method, the weight coefficient of every indicator is confirmed. 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. SDL: added gtk hotkey configuration dialogįCEUX | Free System Administration software downloads at įCEUX 2.2.0 Hits: 426 Size: 8,44 MbįCEUX 2.2.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.SDL: fixed various segfaults and build issues.Win32: Support for HUD recording in AVI dumping.Win32: fixed compare-type cheats and game genie codes.Improved Lua drawing, new Lua functions and scripts.Various bugfixes in movies/replay engine.Win32: Major improvement of debugging tools.Win32: Proper fullscreen support and correct aspect ratio.Huge mappers overhaul, all latest mappers from fceu-mm.The concept behind FCEUX is to merge elements from FCEU Ultra, FCEU rerecording, FCEUXD, FCEUXDSP, FCEUXDSP CE, and FCEU-mm into a single branch of FCEU.Īs the X implies, it is an all-encompassing version of the FCEU emulator that provides the best of all worlds for the general player, the ROM-hacking community, and the Tool-Assisted Speedrun Community. ![]() Over time FCE Ultra had separated into many distinct branches. For pro users, FCEUX offers tools for debugging, rom-hacking, map making, Tool-assisted movies, and Lua scriptingįCEUX is an evolution of the original FCE Ultra emulator. The FCEUX concept is that of an "all in one" emulator that offers accurate emulation and the best options for both casual play and a variety of more advanced emulator functions. It supports both Windows and SDL versions for cross compatibility. It supports both PAL (European) and NTSC (USA/JPN) modes. FCEUX is a Nintendo Entertainment System (NES), Famicom, and Famicom Disk System (FDS) emulator.
