Globalizing a rural past: The conjunction of international development aid and South Korea’s dictatorial legacy

Saemaul Undong is an international development aid model that has recently gained international currency. It originated in a rural development campaign led by a South Korean authoritarian regime in the 1970s. What enabled the campaign’s global transformation, and what are its implications? To answer these questions, this research examines the relationship between dictatorship and development by reviewing the literatures on developmental state, developmental dictatorship, and mass dictatorship. Park Chung Hee’s authoritarian regime employed a discursive strategy of presenting the campaign as an opportunity of contributing to national development—a development defined only in economic terms—and secured participation from rural communities that had desired progress. At the wake of a national debt crisis in the post-authoritarian era, various non-governmental and quasi-governmental actors elevated the campaign into a political and economic imaginary that allegedly merits international replication in their efforts to practice the discourse of national development. This imaginary was institutionalized into an international aid model, which the Park Geun-hye administration abused for its glory. The findings of this research show that, unlike the liberal claim that democracy follows economic development, the legacies of developmental dictatorship may persist through evolution even after formal democratization. Attempts at the uncritical replication of Saemaul Undong in the Global South risk reproducing the reductionist definition of development that overlooks political development. As the country is still paying the cost of its dictatorial legacy, the true lessons from South Korea’s development experience can be found in its prolonged struggle for democracy.     

基于模糊数学的广东大宝山矿横石河下游 土壤重金属元素污染评价

对广东大宝山矿横石河下游地势平坦的农耕区上坝村表层土壤中6种重金属元素进行测试分析,并构建模糊数学污染评价模型对重金属的污染程度进行评价。结果显示,研究区土壤受到重金属Cd、Cu、As的复合污染,显示为重度污染,Cd污染最为严重,Cu、As为轻度污染,传统的综合污染指数和内梅罗综合污染指数评价显示为轻度和重度污染。模糊数学污染评价法有多个影响因子引入,更加符合矿区及周围地区重金属污染的现状,因而能够在矿区及周边地区土壤重金属的污染评价中得到应用,该方法基于传统的污染评价法进行优化和改良,因此具备良好的可操作性和广泛的适用性。     

广东大宝山矿区横石河沿岸水土重金属分布规律及其累积风险

研究矿业活动重金属的释放、迁移及累积特征对于控制和治理矿区水土环境污染具有重要的意义。本文通过广东大宝山矿区水土污染源调查及横石河流域沿岸水土样品采集,以研究区土壤对照值及国家环境质量为标准,试图探讨了大宝山矿区重金属迁移及累积特征。研究结果表明,横石河沿岸土壤重金属元素主要来自采矿活动的酸性废水的排放,土壤中Cd、Pb、Cu和Zn的含量均超过对照值,呈现出明显的累积特征,且Cd、Cu含量超过了国家土壤环境质量标准;土壤中重金属累积程度及其风险等级呈现出从源头向下游递减的特点,其中凉桥、水楼下地段农田重金属处于高风险区,阳河—莲心村虽有累积,但无风险;上坝村地处土壤重金属累积的中风险区,下坝村处于低风险区。研究结果为矿区重金属污染防治提供了重要依据。

空间生产视角下的传统村落空间转型过程、特征与机制——以黄山市卖花渔村为例

基于空间生产的“三元辩证法”视角,以黄山市歙县卖花渔村为例,从物质空间、社会空间和制度空间3个维度分析传统村落空间转型过程、特征及驱动机制。结果表明：1）改革开放以来卖花渔村空间转型经历了内生性缓慢转型发展、外源性空间快速扩展、有序化空间品质提升3个阶段。2）随着盆景产业复兴和乡村旅游业兴起,传统村落物质空间分化重塑、社会空间解体重构、制度空间日趋完善,呈现出空间功能复合化、社会关系开放化、空间主体多元化的空间转型特征。3）在社会关系变迁、资本投入、权力干预等共同作用下,社会空间、物质空间及制度空间互动演进,共同推动了传统村落空间转型过程。     

传统古村落研学旅行游客满意度影响因素研究——以西递、宏村为例

开展传统古村落研学旅行游客满意度影响因素研究,对于构建以人为本的乡村研学旅行产品体系具有重要意义。论文以皖南地区典型的古村落西递、宏村为例,从游客体验视角,构建了研学旅行游客满意度影响因素的结构方程模型,并进行了模型的因素恒等性检验。结果表明：影响西递、宏村研学旅行游客满意度的旅游体验因素有文化认知、情感体验、审美体验和学习认知4种类型;从路径系数来看,案例地研学旅行者的文化认知(0.510)对游客满意度影响程度最大,情感体验(0.340)和审美体验(0.224)次之,学习认知(0.212)位居最后;论文构建的传统古村落研学旅行游客满意度结构方程模型具有跨样本稳定性特征。研究结果可为西递、宏村研学旅行课程开发和传统古村落研学旅行高质量发展提供决策参考。

“Suspending village” a model of new development area in the ningxia hui autonomous region of China

The southern part of the Ningxia Hui Autonomous Region in China was infamous for its poverty and serious soil erosion caused by over population. In order to alleviate poverty and backwardness, a plan was worked out: to remove 200,000 people to the north plain by developing newly irrigated land during the period of 1983–1992. The plan has been in operation for eight and half years to date. About 200,000 people have been removed from the poor southern part to the newly developed area, and 800,000 mu (1/ 15 ha) of desert land has been cultivated. Most of the migrants have been lifted out of poverty and the people ’s life in the south is being improved. During the immigration process, a model, called “Suspending Village”, has been developed. In the article, the whole process of the development and the strategies are discussed.
