- 摘要:
- 运用能值理论与分析方法，采用能值投资率、能值产出率、环境承载力、可持续发展等重要能值指标对贵州省1990—2010年间农业生态系统的能值时空分异进行了分析。结果表明：贵州省农业生态系统能值投入产出呈递增趋势，投入以可更新资源能值和可更新的有机能为主，工业辅助能的增加最为显著，能值产出结构以种植业主，并呈下降趋势；能值投资率和环境承载力高值区主要分布在贵州中西部地区，低值区分布在贵州东南地区；净能值产出率高值分布在贵州东北、西南地区，低值分布在西北；可持续发展指数高值分布在遵义、黔东南和黔西南，低值分布在中西部，能值指标的空间格局分布差异，主要受到经济发展水平、工业能值投入量、人口、农业基础设施的影响。
- Abstract:
- Based on theory and analysis methods of energy, through some indicators of energy, such as energy investment ratio, energy yield ratio, environmental loading ratio, index of sustainable development, this paper analyzed spatiotemporal pattern of energy in Guizhou Province between 1990 and 2010.The results show that the input-output values of agro-ecosystem energy shows an increasing trend, the input value mainly is renewable resources and updatable organic energy. Industrial auxiliary energy significantly increases, the structure of energy output mainly is farming, and it is declining, the energy investment ratio and energy yield ratio of high value area is mainly distributed in the central and western regions of Guizhou, the low value distributes in southeast and southwest region of Guizhou; the high and low values of environmental loading ratio are mainly distributed in northeast and Southwest regions of Guizhou; sustainable development index of higher value is distributed in Zunyi, southeast and southwest of Guizhou, low-value is distributed in the midwest, the differences of spatial pattern of distribution of value is mainly affected by the level of economic development, the industrial value volume, population, and the agricultural infrastructure.
