    摘要:

    [目的] 探寻城镇化快速发展条件下作为生态示范村的陕西省米脂县高西沟村的土地利用转型特征,为陕北黄土高原地区的乡村“三生”空间可持续发展提供参考。 [方法] 通过土地利用动态度、土地利用转移矩阵分析高西沟1953—2022年的“三生”空间特征,并结合实地调研对村域多年“三生”空间格局演变特征及对应的空间治理优化策略展开分析。 [结果] ①1953—2022年,高西沟生产空间呈减小趋势,生活空间和生态空间呈增大趋势。1953—1973年,生态空间变化幅度最大,绿地生态空间从12.07 hm2增加到100.33 hm2,其他生态空间从12.07 hm2减小到100.33 hm2,生产空间逐渐减小,从145.67 hm2减小到110.07 hm2。1986—2022年,生产空间减少了42.4 hm2,生活空间增加了5 hm2,生态空间增加了37.39 hm2。 ②1986—2022年,高西沟“三生”空间转型体现在绿地生态空间和农村生活空间的增加,农业生产空间、其他生态空间和水域生态空间的减少。有67.83 hm2的农业生产空间和59.95 hm2的其他生态空间转化为绿地生态空间,而部分绿地生态空间转化为农业生产空间和农村生活空间,其转移面积分别为21.20和3.22 hm2。 ③高西沟针对生产空间效益不足的问题,采取改变广种薄收的耕种方式,大幅提高粮食产量,改变单一的农业生产状况,实现多种经营模式并存的举措;针对生活空间品质低下的问题,采取全力抓牢基建,量力新建家园,鼓励青年外出,从事其他产业的举措;针对生态空间破坏严重的问题,采取控制水土流失,退耕还林还草,打造旅游文化,推广生态风光的举措。 [结论] 根据早期“三生”空间的主要问题,高西沟做出适宜的优化策略,提高土地利用率,扩大林草面积,使绿地生态空间达到80%。农林牧的高效发展,生产、生活、生态的全面改善,使高西沟成为黄土丘陵区的生态示范代表。

    Abstract:

    [Objective] The characteristics of land use transformation of Gaoxigou village, Mizhi County, Shaanxi Province, an ecological demonstration village under the rapid development of urbanization were studied in order to provide reference for the sustainable development of rural productive-living-ecological space in the Loess Plateau region of Northern Shaanxi Province. [Methods] The dynamic attitude of land use and land use transfer matrix were used to analyze the spatial characteristics of productive-living-ecological space at Gaoxigou village from 1953 to 2022. Combined with field research, the spatial pattern evolution characteristics and corresponding spatial governance optimization strategies were analyzed. [Results] ① from 1953 to 2022, the production space of Gaoxigou village decreased, while the living space and ecological space increased. From 1953 to 1973, the ecological space changed the most, the green space increased from 12.07 hm2 to 100.33 hm2, the other ecological space decreased from 12.07 hm2 to 100.33 hm2, and the production space gradually decreased from 145.67 hm2 to 110.07 hm2. From 1986 to 2022, the production space decreased by 42.4 hm2, the living space increased by 5 hm2, and the ecological space increased by 37.39 hm2. ② From 1986 to 2022, the transformation of productive-living-ecological space at Gaoxigou village reflected in the increase of green space and rural living space, and the decrease of agricultural production space, other ecological space and water ecological space. There were 67.83 hm2 of agricultural production space and 59.95 hm2 of other ecological space transformed into green space, and part of green space ecological space transformed into agricultural production space and rural living space, with the transfer area of 21.20 hm2 and 3.22 hm2, respectively. ③ To solve the problem of insufficient production space efficiency, Gaoxigou village adopt the measures to change the cultivation method of wide planting and low harvest, greatly increase the grain yield, change the single agricultural production situation, and realize the coexistence of multiple business modes; In response to the low quality of living space, Gaoxigou village had taken measures to strengthen infrastructure, build new homes, and encourage young people to go out and engage in other industries. In view of the serious damage to ecological space, measures have been taken to control soil erosion, return farmland to forest or grassland, build tourism culture and promote ecological scenery. [Conclusion] According to the main problems of early productive-living-ecological space, Gaoxigou village made appropriate optimization strategies to improve the utilization rate of land, expand the area of forest and grass, so that the green ecological space reached 80%. The efficient development of agriculture, forestry and animal husbandry, and the overall improvement of production, life and ecology make Gaoxigou village an ecological demonstration representative of the loess hilly region.
