广东省67县域农业经济系统生态效率研究
县域农业是国民经济的基本单元，对县域农业经济系统生态效率进行定量分析可为区域农业资源环境规划与可持续发展提供决策依据。运用能值分析方法，对广东省67县域2000---2010年问的生态效率进行测度，并运用ArcGis913软件对各县域的空间差异进行等级划分与图像表达。结果表明：广东省县域农业的总体自然环境水平较高，生态环境压力不大；系统的产出效率较高，具有一定比较优势，且粤东整体水平高于粤西；系统在与外界市场进行交换的过程中处于盈利地位，可持续发展能力较强。结合研究结果，建议形成以“新丰县一始兴县一佛冈县”为辐射中心的广东省可持续发展农业示范区，并以云安县和蕉岭县作为次中心，带动粤西和粤东地区...

| Bibliography: | LING Li-wen, CHEN Jian-guo, ZHOU Wen-zhi, XU Xiao-hong （ College of Mathematics and Informatics, South China Agricultural University, Guangzhou 510642, China ） 44-1267/S county agriculture; eco-efficiency; emergy analysis; ArcGis9.3 County agriculture is the basic component of national economy. Quantitative analysis of eco-efficiency of county agricultural economic system can provide decision basis to the regional agricultural resource planning and the agricultural sustainable development. Based on emergy analysis method, this paper measured the coo-efficiency of 67 counties in Guangdong province between 2000 and 2010. Spatial variation and grade division images were produced by ArcGis. The results showed that Guangdong county agricultural economic system had a good natural environment as well as a relative high output efficiency. The system had advantages in market exchange activities and gained the substaintial sustainable development capability. According to the research, we suggested to build Guangdong susta |
