广西扶贫开发与城乡协调发展战略探讨

广西石漠化地区人口-资源-环境-发展的矛盾非常突出。2002年,广西农村贫困人口仍有95．6万人,城乡居民收入差异、人均消费支出差异分别为3.43和3．37倍,明显高于同期全国的平均水平,因而是我国贫困人口集中、城乡差距问题突出的区域之一。在分析广西农村贫困化基本状况、发生成因基础上,梳理了近10多年来广西实施就地开发、对口帮扶、异地安置和小额信贷等主要的扶贫开发成功模式,进一步指出新形势下加快扶贫开发和统筹城乡协调发展的必要性,以及促进农村扶贫开发和城乡协调发展的可行战略。

宁夏生态移民村空间剥夺测度及影响因素

生态移民村是一种具有扶贫脱贫与生态保护双重意义的特殊乡村类型,是乡村振兴不可或缺的重要对象。在空间重构过程中形成的空间剥夺现象,是当前生态移民村全面振兴面临的一个新问题。为探究生态移民村空间剥夺规律,以宁夏70个生态移民村2017年相关数据为基础,构建了以收入就业、教育培训、社会生活、居住环境及公共服务可达性为主要内容的空间剥夺指标体系并进行水平测度,进而运用地理加权回归和地理探测器对其影响因子进行探测。结果显示：① 宁夏生态移民村空间剥夺整体水平较低,但总指数均值相对于非生态移民村显著高出0.023;② 宁夏生态移民村空间剥夺时空分异特征明显,总指数均值在时间上呈现“先较低—后上升—再下降”趋势,在空间上呈现“北部低—中部高—南部次高”分布;③ 民族构成、地形地貌、移民时段、依托资源和经济区带是影响生态移民村空间剥夺的重要因子,前3项对空间剥夺总指数的解释力分别达到了22.4%、10.6%和14.0%。空间剥夺水平测度为生态移民生产生活评价和政策调整完善提供新的客观依据,相关部门可据此优化调节生态移民村空间资源配置,增加其获取资源的能力和机会,推动生态移民村全面振兴。     

重庆市乡村生产空间系统脆弱性时空分异与差异化调控

脆弱性作为乡村生产空间系统的重要属性,是探讨系统易受负面影响或损害程度的有效度量、解析系统可持续发展趋势的有效途径。以重庆市为研究区,以2007—2017年为研究时段,建立乡村生产空间系统脆弱性评价指标体系和评价模型,以定量测度乡村生产空间系统脆弱性,揭示其时空分异特征,进而划分脆弱性类型并提出差异化调控策略。结果表明:① 乡村生产空间系统脆弱性是系统运行状态的综合度量,包含暴露度、敏感性和适应能力3个要素,其体现了以“人”为核心的乡村多元主体与以“地”为核心的乡村生产空间之间相互影响、相互作用的互动制衡关系。② 乡村生产空间系统暴露度总体呈上升趋势及“局部突出、北高南低”的空间格局特征;敏感性总体呈波动下降趋势及“东高西低”的空间格局特征;适应能力总体呈快速上升趋势及“西高东低”的空间格局特征;脆弱性总体呈下降趋势及“东高西低”的空间格局特征。③ 将重庆市乡村生产空间系统脆弱性划分为适应能力脆弱型、暴露—敏感脆弱型、敏感—适应脆弱型和强综合脆弱型4种类型,并按照“生态优先—分类调控—重点突出—因地施策”原则针对不同类型提出差异化“降脆”策略,以引导乡村生产空间系统可持续发展。     

农户的非农就业如何影响中国的土地流转?

To clarify the impact of non-agricultural employment on rural land circulation in China,we built logit models using the Chinese Household Income Project 2013 dataset,which includes 18,948 household samples over 15 provinces,126 cities and 234 counties of China in 2013.We use the proportion of non-agricultural income,the proportion of non-agricultural laborers and non-agricultural fixed operating assets to reflect the degree of the households’dependence on agriculture,the degree of the households’laborers committed to non-agricultural employment and the stability of non-agricultural employment,respectively.The results show that the stability of non-agricultural employment is an important reason for farmers to transfer out their land,and an increase in non-agricultural income is the fundamental reason.The proportion of non-agricultural assets has the greatest impact on the decision to transfer land,followed by the proportion of non-agricultural income.Per unit increase in the non-agricultural income ratio has a stronger effect on the transfer-out decision than it does on the transfer-in decision,which is a 0.09 increase of the probability of transfer-out the land and a 0.07 decrease of the probability of transfer-in the land.In terms of regional differences,when considering the impact of non-agricultural employment on the land transfer-out decision,the impacts of non-agricultural income and labor force are the greatest in the Central region.The impact of non-agricultural assets is the greatest in the Eastern region.For the Eastern region,the decision to transfer out land is mainly affected by non-agricultural assets and the non-agricultural labor force,and the decision to transfer in land is mainly affected by non-agricultural assets.In the Central and Western regions,the decision to transfer out land is mainly affected by non-agricultural assets,non-agricultural income and the non-agricultural labor force,in that order.The decision to transfer in land in the Central region is not significantly affected by non-agricultural employment.The decision to transfer in land in the Western region is mainly affected by non-agricultural assets,non-agricultural labor force and non-agricultural income,in that order.We note that non-agricultural assets have a prominent impact on land transfer,which shows that the stability of non-agricultural employment has an important impact on land transfer decision-making.Vocational training for rural labor forces may be an effective means to promote stable non-agricultural employment and simultaneously facilitate rural land circulation,especially in Central and Western China.

Space Changes in the Rural Tourism Area of Mufu Town,Hubei Province,China

In a society dominated by tourism consumption, space changes occurring in rural areas can generally reflect their social changes. On the theoretical basis of flow, regeneration and adaptation of rural tourism space, this paper originally and creatively proposes that the spatial elements in a rural tourist area can be classified into three categories: Attractions (A), Towns (T) and Villages (V). By analyzing the spatial transformation characteristics of A, T and V, five types of rural spatial transition modes are found, the types of heritage, theme park, those serving as scenic spots, leisure industrial clusters and ecotourism areas. These different classes emerge due to their geographical differentiation. They show the same spatial evolution trend: The Attractions are distributed throughout the whole area and characterized by diversification; supporting services facilities gather in the Towns; and the Villages are landscape images. In this area the traditional rural benefit trends toward that of compound development. Mufu Town, Hubei province, is taken as a study case, and the changing characteristics of A, T and V from 2006 to 2016 are described. Problems in the process of establishing the new spatial order are considered. In order to realize the synergy between production space, living space and ecological space, the interactive development between Attractions, Towns and Villages is recommended. The perspective of Attraction-Town-Village (ATV) can lead to a better understanding of the situation of tourism space in rural areas and provide directions for thinking about the reconstruction path for the modernization of traditional societies.
