农村居民点用地布局优化不仅是农村土地整治的基础,也是新农村建设和实现美丽乡村的重要路径。该文以江苏省宜兴市为例,根据其经济发达、生态环境优越以及风景名胜众多的特点以及农村居民点用地特征,运用景观安全格局理论和最小累积阻力模型相结合的方法,分别从水土保持、生物多样性保护和风景名胜保护三方面构建单一景观安全格局,进而建立宜兴市农村居民点用地布局综合景观安全格局。通过与宜兴市农村居民点用地的叠加分析,针对不同景观安全水平的农村居民点提出不同的布局优化方向,将宜兴市农村居民点用地划分为优先整治型、限制扩展型、适度建设型、重点发展型4种类型,分析各类型现状特征并提出优化方案。研究结果强调农村居民点用地布局工作中生态环境和景观保护优先的思想,不仅为当地新农村建设提供理论支撑,而且为相关规划制定提供参考。
農村居民點用地佈跼優化不僅是農村土地整治的基礎,也是新農村建設和實現美麗鄉村的重要路徑。該文以江囌省宜興市為例,根據其經濟髮達、生態環境優越以及風景名勝衆多的特點以及農村居民點用地特徵,運用景觀安全格跼理論和最小纍積阻力模型相結閤的方法,分彆從水土保持、生物多樣性保護和風景名勝保護三方麵構建單一景觀安全格跼,進而建立宜興市農村居民點用地佈跼綜閤景觀安全格跼。通過與宜興市農村居民點用地的疊加分析,針對不同景觀安全水平的農村居民點提齣不同的佈跼優化方嚮,將宜興市農村居民點用地劃分為優先整治型、限製擴展型、適度建設型、重點髮展型4種類型,分析各類型現狀特徵併提齣優化方案。研究結果彊調農村居民點用地佈跼工作中生態環境和景觀保護優先的思想,不僅為噹地新農村建設提供理論支撐,而且為相關規劃製定提供參攷。

Rural residential land layout optimization not only provides a foundation for rural land consolidation, but also plays an important role in the New Countryside Construction and Beautiful Village programs. As an important land use type, rural residential land accounts for a large proportion of construction land in China. Numerous studies have shown that the layout of rural residential land is influenced by physical, economic and social factors, whose impacts vary across different regions. Yixing city, located in the developed southern region of Jiangsu province is chosen as the study area. As economic factors are no longer the dominant factors limiting rural residential land layout in Yixing city, other factors such as ecological preservation and scenic resources conservation exert more influence instead. According to the theory of landscape security pattern, some point elements, linear elements and surface elements in space play essential roles in the formation of regional landscape, and thus combine to form the regional landscape security pattern. In this paper, the theory of landscape security pattern is applied in the optimization of rural residential land layout in Yixing city, focusing especially on consideration of ecological preservation and scenic resources conservation. <br> Firstly, some critical plaques are selected as the sources for soil and water conservation, biodiversity protection and scenic resource conservation. Secondly, influencing factors are chosen to set up a resistance surface for the above mentioned conservation and protection objectives based on the values of influencing factors. Thirdly, an individual landscape security pattern for the three objectives is constructed via the minimum cumulative resistance model and Cost-weighted tool. Furthermore, a comprehensive landscape is obtained with four security levels. Finally, layout optimization schemes are presented after the overlaying of the rural residential land map of 2010 and the comprehensive landscape security pattern map. Rural residential land in Yixing city is divided into four types including prior remediation, expansion-control, moderate construction, and key development, which accounts for 6.79%, 17.90%, 53.18% and 22.13% of the total land area, respectively. Prior remediation land is characterized by steep slopes and is a superior ecological environment with parts being primeval forest and habitats of wildlife. It’s suggested that villages on these lands should be moved. Expansion-control land is characterized by complicated topography consisting of low mountains and hills, and poor agricultural production and living conditions, and is located adjacent to the wildlife habitats. It’s suggested that construction activities on these lands should be strictly controlled, and the population should be moved out gradually. Moderate construction land is characterized by gentle terrain, and superior infrastructure far away from the wildlife habitat. We suggest a reasonable layout of rural residential land on these lands. Key development land is characterized by flat terrain, convenient transportation, and superior agricultural production conditions. We suggest development activities with high intensity on these lands. With priorities focusing on the ecological environment and landscape protection, our study provides theoretical guidance not only for New Countryside Construction, but also for related planning formulation.
