基于土地规模经营条件评价的村域生产空间格局厘定————以重庆市合川区大柱村为例

新型农业经营主体入驻形成的生产空间格局既可发挥村落资源禀赋能力,保障农民就地就业,又能促使村域生产空间集约高效目标实现.以整村推进示范村重庆市合川区大柱村为研究对象,构建以自然,区位,设施,劳动力,流转等为限制性条件的土地规模经营条件评价指标体系,利用自然断裂法(Jenks)对耕地图斑进行5级分类,以集中连片为划分原则,以充分利用村域资源禀赋为目标,将大柱村生产空间厘定为四个区域:优势区,良好区,中等区,较差区,相应提炼出农业企业示范区,农业企业发展区,专业大户集聚区和特色家庭农场区的新型农业经营主体入驻格局,为充分发挥西南丘陵山区村域资源禀赋,开展适度规模经营,引导生产空间重构提供理论指导与实践借鉴.

Redefinition of patterns of production space on village scale based on evaluation of the land scale operation conditions for Dazhu Village,Chongqing

The patterns of production space formed by the new main bodies of agricultural management can play the ability of resource endowment of villages,guarantee farmers employ locally,and promote the intensive and efficient target of production space of villages to complete. Here,we take the Dazhu Village in Hechuan District,Chongqing as a case study and build an index system of evaluation about natural conditions,location conditions,facilities conditions,labor force conditions and circulation conditions (restrictive conditions). Then,we use the method of natural fracture(Jenks)to reclassify the evaluation results of arable land to 5-grade. Based on the spatial distribution of the above grading results,with concentration and continuity as the classification principles,we redefine the patterns of production space for Dazhu Village into four areas (advantage area,good area,middle area and poor area) and extract four patterns formed by the new main bodies of agricultural management (e.g. demonstration area of agricultural enterprise,the development area of agricultural enterprise,the gathering area of professional investors and the family farm area with features). These results can provide theoretical guidance and practical reference regarding the aspects of resource endowment using of villages in hilly and mountain areas,moderate scale management,and the reconstruction of production spaces in villages.
