【摘要】：区域的低碳发展是科学界关注的热点。本文以中国301个地级行政区为基本单元建立量化指标体系,把2011年中国低碳发展水平分为4个一级类型和8个二级类型,并通过Moran指数与散点图、LISA集聚图,结合基于扩展断裂点模型的中国经济区划分方案,分析低碳发展类型的宏观和局域分异特征,对于制定有针对性的不同类型区低碳发展政策具有重要意义。研究表明,中国低碳发展以高碳和相对高碳类型为主,一级经济区内低碳发展类型多样化分布,而大多数二级经济区内低碳发展类型具有相近性。依赖于高耗能产业结构的LLL和LHL类型在胡焕庸线上方和沿线集聚分布,而低碳经济与社会发展动力不足的LLH类型主要分布在胡焕庸线下方。低碳和相对低碳类型位于胡焕庸线下方,特别是在东部沿海和长江中游地区大量分布。在局域空间,各子系统发展存在着很强的正向空间依赖,低碳经济与社会发展以"LL"型集聚为主,但后者的空间异质性较强,而低碳环境发展则以"HH"型集聚为主。各子系统发展的热点区大多位于中国东部和南部且较为独立,冷点区则有所重叠,主要位于内蒙古西部及西北经济区连片地区。
[Abstract]:Regional low-carbon development is the focus of scientific attention. This paper takes 301 prefectural administrative regions in China as the basic unit to establish a quantitative index system. The low carbon development level of China in 2011 is divided into four primary types and eight secondary types, and through the Moran index and scattered plot map Lisa agglomeration map. Based on the extended fracture point model, this paper analyzes the macroscopic and local differentiation characteristics of low-carbon development types. The research shows that the low carbon development in China is dominated by high carbon and relatively high carbon types, and the distribution of low carbon development types in the primary economic zone is diversified. The low carbon development types in most secondary economic zones are similar. The LLL and LHL types, which depend on the high energy consumption industrial structure, gather and distribute above and along Hu Huanyong line. The low carbon economic and social development of the LLH type is mainly distributed under Hu Huanyong line. Low carbon and relatively low carbon type is located below the Hu Huanyong line. Especially in the eastern coastal areas and the middle reaches of the Yangtze River, there is a strong positive spatial dependence on the development of each subsystem in the local space, and the low carbon economy and social development is mainly "LL" type agglomeration. However, the latter has strong spatial heterogeneity, while the low carbon environment development is mainly "HH" type agglomeration. Most of the hot spots of each subsystem are located in the east and south of China and independent, and the cold spots are overlapped. Mainly located in the western part of Inner Mongolia and the Northwest Economic Zone.

【正文快照】： 1引言低碳发展(Low Carbon Development,LCD)已经成为各国应对全球气候变化的重要适应策略。然而,目前国际上对低碳发展的内涵尚未达成一致[1]。因各国巩固其发展重点的经济和社会方案迥然不同,在国际尺度上对低碳发展定义加以严格的规范不但十分困难,而且是不必要的。最近的
