摘要:
以福建省三明市宁化县为研究区,以1∶5万地质调查成果为数据支撑,采用限制因子法对农业生产适宜性指标进行加权求和,开展了县级尺度农业生产适宜性评价工作,得到农业生产适宜性评价等级。研究表明:宁化县现状耕地资源配置总体较合理,但仍有3.54%的现状耕地是农业生产不适宜区;红层区易发生水土流失,对当地生态环境造成严重影响;局部地区土壤厚度较薄,阻碍了作物根系下扎延伸,土壤保水保肥能力差,不适宜农业耕作;梯田分布广泛,梯田耕作平台规整,土壤厚度较厚,可作为山区耕地资源的有效补充。该研究为县级国土空间规划提供专项技术支撑,有利于农业生产格局优化。
Abstract:
Based on 1∶50 000 geological survey results in the area, this paper adopts limiting factor method to weight and sum the agricultural production suitability indexes, evaluates and grades the county-level agricultural production suitability of Ninghua County, Sanming City of Fujian Province. The current resource allocation of arable land in Ninghua County was reasonable in general, and 3.54% of the cultivated land belongs to the unsuitable area. The red bed area of Ninghua was prone to water and soil loss, especially the plantation of oil tea and other crops, posing a serious impact on the local ecological environment. Since the relatively thin thickness of the soil in some plots hindered the downward growth and extension of crop roots, this kind of soil was unfavorable to conserve water and fertilizer, and was not suitable for agricultural cultivation. In addition, terraces are widely distributed in Ninghua with regular farming platform and thick soil thickness, and can be used as an effective supplement to cultivated land resources in mountainous areas. The suitability evaluation of agricultural production can provide special technical support for county-level land spatial planning and is conducive to the optimization of agricultural production pattern.
