一堂别开生面的避险课

日前,方城县第二次土地调查中的农村调查全面完成,其中一项统计结果令人吃惊：该县耕地总面积较第一次土地调查统计结果整整多出27万亩127万亩耕地是一个什么概念？按该县目前人均1．4亩的耕地占有量计算,等于增加了19．3万人的口粮田;按夏秋两季亩均产粮1500公斤计算,意味着每年粮食增产40多万吨,其经济、社会效益何等显著,由此可见一斑。

纽约社区花园的发展经验与启示（英文）

在高密度的城市环境下,居民对增加绿地面积、提升社区环境品质以及重建居民关系的迫切需求催生了社区花园这一新的空间类型。但我国尚缺少相关经验,而纽约社区花园建设起步较早,在空间建设和运营维护上都有着丰富的经验,可以为我国社区花园发展提供参考。本文首先采用文献计量研究方法,以2000–2020年Web of Science核心库的201篇期刊文献为研究对象,借助CiteSpace软件分析,得到纽约社区花园的研究热点从宏观研究向空间类型、营造方式、社会影响等研究转移;之后结合研究历程分析与实地调研访谈结果,对纽约社区花园的空间建设发展现状及社会组织建设发展现状进行探究,总结出纽约社区花园发展的有效经验。针对我国社区花园的发展现状,提出中国社区花园应以保障发展用地、发挥社会效益、调动社会组织力量为导向进行发展,从而成为城市空间建设和社会治理的有效途径。     

LAND USE CHANGE AND ITS SOCIO-ECONOMIC DRIVING FORCES UNDER STRESS OF PROJECT IN OLD RESERVOIR AREA —— Case Study of Linshui Reservoir Area of Dahonghe Reservoir in Sichuan Province

The old reservoir areas built in 1950s- 1970s left behind many socio-economic problems, because of the administrative backward migration and little migration fund, and all these problems would be tied to land. Based on interviewing with peasant households, combining land use survey and socio-economic statistical index, this paper analyzed land use change and its corresponding driving forces in Linshui reservoir area of Dahonghe Reservoir. Results showed that land use change in the reservoir area was mainly embodied on low-lying land submergence and migration requisition land. The former changed the land use patterns, and the latter mainly reconstructed original land property and made land over-fragmented. Cultivated land per capita was 0.041ha in this area, below the cordon of cultivated land per capita enacted by FAO. Currently, there were still 30.25% of peasant households being short of grain in trimester of one year, and there were 35.27% of people living under the poverty line. The conditions of eco-environmerit in Linshui Reservoir Area were worse, and healthy and sub-healthy eco-environment accounted for less proportion, composed of green belt around the reservoir area and paddy field ecosystem, and economic forest and orchard ecosystem, respectively. The stress of the reservoir project was macroscopic background to analyze the driving factors of land use change, and real underlying diving factor of the land use change in the area was the change of cultural landscape under the stress of reservoir project. The rapid increase of population was the key factor to induce the change of man-land relationship in the reservoir area, the low level of rural economy was the crucial factor to decide how migrants input for production, and the belief of migrants, influencing the land use patterns in a certain extent, was the inducing factor to keep land use stable. The low-lying submergence and infrastructure construction accompanied the reservoir project were leading factors driving land use change in the area, while changes in land use patterns, after the reservoir being built, were the responses of peasant households＇ behaviors to land use change.
