| 中文摘要 | 石漠化制约着云南、贵州、广西三个省区的发展。应用能值分析法,以经济和环境资料为主,辅以遥感和GIS获取能值分析所需的数据,编制能值分析表,计算2000和2009年典型石漠化地区生态经济系统能值流,得出石漠化省区资源环境能值、环境负荷率(ELR)、能值产出率(EYR)、能值产出比(ENR)等统计指标,进一步计算构建可持续指数(ESI)、改进的可持续指数(MESI)和可持续年限(ST)等指标。2009年广西、贵州、云南的主要资源环境能值分别为9.6E+25、1.2E+26、1.5E+26sej,可更新资源能值为9.9E+22、7.3E+22、2.0E+23sej,废弃物能值2.1E+22、1.1E+22、1.4E+22sej。结果表明:石漠化地区的ESI和MSEI都具有经济落后地区的显著特征,其ESI的时空演变趋势(0.07)显著低于全国ESI的平均趋势(0.41),石漠化地区可持续发展要稍好于全国平均值,而区域可持续年限从2000年的平均超过100年缩减为2009年的不足50年。 |
| 英文摘要 | In essence,Karst rocky desertification is a land degradation hazard because of anthropic and natural factors. Karst rocky desertification has restricted the economic growth of underdeveloped area in Yunnan, Guizhou and Guangxi provinces. The remaining time that the full resources in karst rocky desertification area can support has been reducing rapidly. In order to explore effective approaches to sustainable development,the economic and environmental data from statistical annual,RS and GIS technologies were applied to establish emergy analysis table,and then emergy of eco - economic system for typical areas of Karst rocky desertification in 2000 and 2009 was calculated using emergy analysis method. The emergy results were classified statistically as emergy of resources and environment,environment load rate (ELR),emergy yield rate (EYR),emergy output rate (ENR),and wastes load rate (WLR). Such indices were used to establish the emergy sustainable indices (ESI),modified emergy sustainable indices(MESI) and sustainable time(ST). The values of resources and environment emergy,the renew resources emergy and wastes emergy in 2009 were 1E + 26,1. 2E + 26,1. 6E + 26,9. 9E + 22,7. 3E + 22,2. 0E + 23,2. 1E + 22,1. 1E + 22,1. 4E + 22 respectively. The results showed that ESI and MESI in Karst rocky desertification area kept the obvious characteristics of underdeveloped area,and the temporal and spatial trend value(0. 07) of the indices in the area was significant less than the national average trend value(0. 41). Sustainable development in Karst rocky development area was better than others,and ST value was reduced from more than 100 in 2000 to less than 50 in 2009. Consequently,some advices consisting of economic model reform,industrial restructuring and population policy were put forward. |
