摘要:

深入开展乡村地域土地利用变化和聚落发展规律的研究对于探究乡村地域系统优化、推进城乡融合与乡村可持续发展具有重要意义。论文以延安市碾庄流域为例,基于ENVI和GIS等软件技术,结合Landsat卫星影像、马尔科夫链模型和实地调查,从土地利用转移与交换变化、建筑用地空间转移、社会响应等角度探讨了黄土丘陵沟壑区典型村域土地利用变化特征以及对区域乡村发展转型的影响。研究表明:① 在一系列生态工程措施作用下,碾庄流域生态覆被发生明显改观,主要表现为大量的坡耕地及稀疏生态用地转化为林地,其中,林地面积占比由32.34%(2009年)增加至50.88%(2018年);② 在社会经济发展和延安新城“边缘效应”的影响下,碾庄建设用地呈现向流域的东南和西南方向拓展的趋势,10 a间建设用地面积增加了近75%;③ 在人类活动的主导作用下,黄土丘陵沟壑区的乡村正在朝着生态化和集约化的方向转型发展。研究结果有望为深入理解黄土丘陵沟壑区乡村地域系统结构和优化提供新参考。

Abstract:

In-depth research on rural land use change and settlement development is of great significance for exploring the optimization of regional rural system, promoting urban-rural integration, and rural sustainable development. This study took the Nianzhuang gully basin in Yan'an City of Shaanxi Province, China as an example. Based on software technologies such as ENVI and GIS and combining Landsat satellite images, the Markov chain model, and humanistic field survey, this study examined the land use change of typical villages in the loess hilly and gully region and its implications for regional rural transformation and development from the perspectives of change and transfer of land-use types, spatial change of construction land, and social responses. The results show that: 1) With the implementation of a series of ecological engineering measures, the ecological land cover of the Nianzhuang gully basin has been significantly improved. This is mainly represented by the conversion of a large number of slope farmland and dispersed ecological land into forest land, as a result of which the proportion of forest land area increased from 32.34% in 2009 to 50.88% in 2018. 2) Under the influence of the social and economic progress and the development of Yan'an New City, the construction land of the Nianzhuang gully basin has been expanding into the southeast and southwest of the basin. The area of construction land has increased by nearly 75% in the past 10 years. 3) Due to the leading role of human activities, the villages in the loess hilly and gully region are transforming towards ecological and intensive use of land. The results of this study can provide a new reference for an in-depth understanding of regional rural system structure and optimization in the loess hilly and gully region.
