    Optimization of settlement pattern of Honghe Hani terrace based on surface farming radius and MaxENT model

    • 摘要: 乡村聚落格局优化是土地整理的一项重要工作,对缓解区域人地矛盾,解决 "三农"问题,实现区域可持续发展具有重要意义。该文以红河哈尼梯田世界文化遗产所在地元阳县为研究区,采用曲面距离法计算耕作半径,以景观连接度和缓冲区法计算耕地重叠区(耕作强度),再结合耕作通勤时间计算得到哈尼梯田区的适宜耕作半径。然后依据遗产保护要求与适宜耕作半径识别出聚落格局整理区,引入生态模型MaxENT,以气候、地质地貌及社会经济等4大类的11个因子为数据源模拟得到新增聚落的空间位置,提出聚落格局优化建议。结果表明:1)基于曲面距离和耕作重叠计算得到的全县最适宜耕作半径为1 041 m。2)依据遗产保护和适宜耕作半径分析识别出需要进行聚落格局优化的区域为遗产核心区的新街镇、小新街乡,其余地区为聚落低密度区。3)通过MaxENT模型分析影响聚落分布的因子表明,遗产区为气候因子即降水和气温、小新街乡为气温和旅游中心距离,聚落低密度区则为海拔和岩性。4)MaxENT模型模拟的新增聚落空间位置及格局优化表明,遗产区内潜在适宜聚落区面积为18.42 km2,其中核心区内聚落根据遗产保护条例整体保留,新增人口可外迁至缓冲区(沙拉托乡)内的潜在适宜区;小新街乡内潜在适宜聚落用地面积为9.26 km2,区内聚落就近迁入潜在适宜区;其余聚落低密度区内的潜在适宜居住面积为92.26 km2,在潜在适宜区内选址聚集为2~3个聚落群。该文研究结果可为哈尼梯田基本农田改造、撤村并点、遗产保护规划、聚落空间结构调整提供科学参考。

       

      Abstract: Rural settlements are the main place for human production and life, and their distribution pattern is a reflection of natural, social, economic and historical development. The current rapid urbanization and the decline of traditional agricultural status have made the rural settlements face a crisis of hollowing out or even disappearing. Therefore, the optimization of rural settlement pattern has become a hot issue in global rural research. Optimization of rural settlement pattern is an important work in land consolidation, which is of great significance in alleviating regional conflicts between human and land, solving the problems of “agriculture, rural areas and farmers” and realizing regional sustainability. We took Honghe Hani Terraces World Heritage as the study area, which is located in Yuanyang County of Yunnan province. Firstly, we calculated the distance between settlements and farmland by surface distance method, calculated the overlap degree of farmland by landscape connectivity and buffer method, and then combined the two above with cultivation commuting time to confirm the optimum cultivation radius. Secondly, we identified the planning area of settlement pattern through optimum cultivation radius and the protection regulations of world heritage. Finally, the planning scheme of settlement pattern was proposed based on the potential habitable area that were calculated through eleven physical and human indicators (such as DEM, slope, population) within ecological MAXENT model. The results showed that: 1) The optimum cultivation radius was 1041m. Within its range, the farmland accounted for 75%, the increase of overlap farmland was less than that of farmland, and the cultivation commuting time was less than 20 minutes. 2) Planning area included world heritage area, Xiaoxinjie town and low-density settlements area in the south and north of Yuanyang County. In the world heritage area, population growth of 63.2% from 2005 to 2016 required housing expansion, but it limited strictly by world heritage regulations. In the Xiaoxinjie town, the maximum kernel density of settlements was 1.1 and the overlap farmland area accounted for 7.5% of the county. In the low-density settlements area, the buildings were scattered, the infrastructure was not complete, and the management was unreasonable. Generally, the problems of housing, farmland and management in the planning area need to be specific solved. 3) In the world heritage area that included core area and buffer was 18.42 km2. The settlements in the core area should be entirely preserved according to world heritage regulations and the new populations should be relocated to potential habitable area of heritage buffer or Salatuo. In Xiaoxinjie town, the potential cultivable area was 9.26 km2, which was suitable for settlement and reclamation of farmland. In the low-density settlements area, the potential cultivable area was 92.26 km2. The scattered buildings can be gathered into 2-3 settlements, which were convenient for management and infrastructure construction. The original settlements and farmland could convert into forest and grass. The paper can provide scientific planning suggestions for the reconstruction of farmland and settlements and the protection of world heritage in Yuanyang County.
