摘要:

基于资源环境承载力的农业生产空间评价是新时期国土空间规划中农业空间优化调整的前提,是科学划定农业空间和永久基本农田的必要依据,对保障国家粮食安全和生态安全具有重要意义。构建基于资源环境承载力的农业生产空间评价指标体系,提出资源环境承载力集成方法和农业生产适宜性评价模型,并以福建省为案例开展应用研究。研究表明:农业生产功能指向的资源环境承载力评价包括土地资源类、水资源类、环境类、自然灾害类4种属性的自然要素,依次采用耕种条件、供水条件、环境条件、气象灾害危险性等指标刻画;农业生产适宜性则在承载力分级结果基础上,纳入空间形态类、区位条件类、生产条件类指标,建立适宜性评价模型进行评价;福建省资源环境承载力的高、较高、中等、较低以及低等级比重依次为29.86%、16.27%、12.04%、18.91%和22.91%,高和较高等级区分布于滨海平原、台地及低丘缓坡以及内陆地区的河谷、盆地及山间缓坡区域,全省农业生产适宜区、一般适宜区和不适宜区的比重依次为36.36%、26.76%和36.88%,适宜区具备从事农业生产活动的资源环境综合条件、且田块完整性和耕种便利性优良。案例应用表明,基于资源环境承载力的农业生产空间评价流程可操作性强,可满足农业空间备选区试划需求,已在国土空间规划“双评价”中得到应用;根据承载力与适宜性的“双评价”结果,可按照保留型、整治型和退出型,分类实施农业生产空间优化与整治。

Abstract:

The evaluation on agricultural production space based on resources and environmental carrying capacity is a necessary basis for scientifically delineating agricultural space and permanent basic farmland, which of great significance for national food security and ecological security. In this regard, this article puts forward an efficient and reliable method for delineating agricultural space and assessing the production capacity, which integrates the technical frame of resources and environmental carrying capacity evaluation with the model of suitability assessment for agricultural production, taking Fujian Province as a case study. The results indicate that: 1) the evaluation method should include four crucial elements: land resources, water resources, environment, and natural disasters, which are respectively indicated by cultivation condition, water supply condition, environmental condition, meteorological hazards. 2) Based on the results of carrying capacity grading, suitability for agricultural production needs to consider the spatial form, location conditions, and production conditions. 3) The proportion of spaces with high, sub-high, medium, sub-low, and low grades of resources and environmental carrying capacity in Fujian are 29.9%, 16.3%, 12.0%, 18.9% and 22.9%, respectively. The spaces with high and sub-high grade are distributed in coastal plains, terraces, and gentle hillside, as well as valleys and basins in inland areas. 4) The proportion of agricultural production suitable zone, general suitable zone and unsuitable zone are 36.4%, 26.8%, and 36.9%, respectively. The suitable zone has comprehensive resources and environmental conditions for agricultural production activities, with excellent structural integrity and cultivation convenience. 5) As suggested by this study, the method of delineating agricultural production space based on resources and environmental carrying capacity evaluation, can meet the needs of agricultural production space zoning and planning, which has been applied in the national territorial spatial planning. According to the results of the “double evaluations” on carrying capacity and suitability, the layout optimization and land consolidation of agricultural production can be implemented, targeting at types of reserved type, remediation type, withdrawal type, etc.

Key words: resources and environmental carrying capacity, agricultural production space, suitability for agricultural production, layout optimization
