基于云南省40个生态脆弱县的全样本数据,运用DEA-BCC模型、Moran’s I指数、地理加权回归模型探究云南省生态脆弱县经济效率的空间属性和影响因素,为提升区域抵御内外部风险能力,稳定脱贫成效,加快乡村振兴步伐,步入高质量发展之列服务... 基于云南省40个生态脆弱县的全样本数据,运用DEA-BCC模型、Moran’s I指数、地理加权回归模型探究云南省生态脆弱县经济效率的空间属性和影响因素,为提升区域抵御内外部风险能力,稳定脱贫成效,加快乡村振兴步伐,步入高质量发展之列服务。研究结果表明:(1)云南省40个生态脆弱县的平均经济效率处于中上水平,其中乌蒙山区和滇西边境山区的经济效率较低。(2)云南省生态脆弱县经济效率的空间集聚性弱,近似随机分布,且生态脆弱县主要分布在云南省边缘地带。(3)县域经济效率主要受到务工人口数占比、村集体收入、人均耕地面积等的影响,尽管不同区域的主导因素有所区别,但经济发展总体处于“U”型关系的前端,县域规模效益还未彰显。由此建议通过进一步提高帮扶投入精准度,加强普通教育、职业教育和技能培训,壮大集体经济,推进县域经济效率的提升。 展开更多

Guazhou County of Gansu Province is a typical ecological fragile area lying in the transition area of desert and oasis.The development of its agricultural economy is highly dependent on natural resources and environment.Contradiction of resources characterized agriculture and the fragile ecological environment has become one of the main barriers to log the impact of local agriculture to achieve sustainable development.Aiming at fragile ecological environment and limiting factors of agricultural sustainable development,thoughts and countermeasures of realizing agricultural sustainable development have been proposed. 展开更多

Changting County is located in western Fujian province. Natural, social and economic aspects of ecolog- ical restoration were studied in this area from 2000 to 2011, and the results are widely representative of subtropical mountain ecosystem fragility across China. Great attention should be paid to the application of system theory and the harmony of human-nature relationships. This paper aims to provide the scientific theory to support strategies known as 'harmony of man with nature', which means exerting natural regenesis potential by following natural law, transferring runoff from harm to benefit by operating on the ground and making material and economic virtuous cir- cles in land utilization by arousing human initiatives. It is necessary to transform ideas, tactics and technology and break technological bottlenecks, space limitations and systemic obstacles. 展开更多
