摘要
新型农业经营主体是推动小农户和现代农业有机衔接的新型农业发展类型,其空间分布影响现代农业产业发展空间布局和产业振兴发展格局。基于新型农业经营主体POI数据,利用核密度分析、多距离空间聚类分析和缓冲区分析等GIS空间分析法,对滕州市新型农业经营主体空间分布特征进行研究。结果表明:滕州市各镇街新型农业经营主体分布数量类型有差异,新型农业经营主体分布数量较多的镇街分别为中心城区各街道、姜屯镇、界河镇;核密度分析表明滕州市新型农业经营主体整体呈现“中心—外围”分布特征,外围呈现多组团分布特征。中心城区为主要聚集点,其他区域呈小聚集组团分布,例如界河镇、大坞镇和姜屯镇;多距离空间聚类分析表明滕州市新型农业经营主体在不同空间尺度下均为显著聚类分布,农业企业、农民专业合作社和家庭农场最高聚集点分别在4.25 km、6.63 km和7.83 km观测处;圈层结构分布分析显示滕州市新型农业经营主体整体既呈近中心城区分布,峰值在5 km范围内,又呈近道路、近水路分布,峰值在0~2 km范围内,分布数量分别占总数的93.12%和73.61%;垂直结构分布特征分析表明滕州市新型农业经营主体分布呈现离山地远、离平原近的分布特征,整体分布在海拔50~100 m地带,分布数量占总数的67.61%。
The new-type agricultural management bodies are the new type of agricultural development which promotes the organic connection between small farmers and modern agriculture.Its spatial distribution affects the spatial distribution of modern agricultural industry development and the pattern of industrial revitalization and development.Based on the POI data of new-type agricul tural management bodies,the spatial distribution characteristics of new-type agricultural management bodies in Tengzhou City were studied using GIS spatial analysis methods such as kernel density analysis,multi-distance spatial cluster analysis and buffer analysis.The results showed that there were differences in the distribution quantity and type of new-type agricultural management bodies among towns streets in Tengzhou City.The towns and streets with large distribution quantity of new-type agricultural management bodies were the streets in central urban area,Jiangtun Town and Jiehe Town respectively.The kernel density analysis showed that the overall distribution characteristics of new-type agricultural management bodies in Tengzhou City presented the distribution characteristics of“center-periphery”,and the periphery presented the distribution characteristics of multiple groups.The central urban area was the main gathering point.Other areas were distributed in small clusters,such as Jiehe Town,Dayu Town and Jiangtun Town.The multi-distance spatial cluster analysis showed that the new-type agricultural management bodies in Tengzhou City had significant cluster distribution at different spatial scales.The highest aggregation points of agricultural enterprises,farmers'specialized cooperatives and family farms were 4.25 km,6.63 km and 7.83 km respectively.The analysis of the distribution of the circle structure showed that the new-type agricultural management bodies in Tengzhou City was distributed near the central urban area,with the peak value in the range of 5 km.It was distributed near the road and waterway with the peak value in the ra
