利用网格法确定县域农田整治优先度
为了科学测算农田整治难度系数,合理确定不同评价单元整治的优先次序,该文根据研究区域农田整治特点,以江苏省宝应县为例,以规则网格为评价单元,从土地利用结构、农田空间格局、可提高生产能力、土壤环境质量、人口社会因素等5个影响因素,构建农田整治优先度评价指标体系。对研究区按1′×1′的经纬度网格划分的532个网格评价单元进行农田整治优先度测算,并根据计算结果,按整治优先顺序将整个研究区划分为近期、中期和远期网格单元,分别占42%、31%和27%。远期网格单元分布在宝应县中部和南部的平原区,该区域农田的连片性、细碎度和质量等别等优于其他区域。研究结果表明,该文提出的区域农田整治优先度评价方法,有助于确...

Summary: | 为了科学测算农田整治难度系数,合理确定不同评价单元整治的优先次序,该文根据研究区域农田整治特点,以江苏省宝应县为例,以规则网格为评价单元,从土地利用结构、农田空间格局、可提高生产能力、土壤环境质量、人口社会因素等5个影响因素,构建农田整治优先度评价指标体系。对研究区按1′×1′的经纬度网格划分的532个网格评价单元进行农田整治优先度测算,并根据计算结果,按整治优先顺序将整个研究区划分为近期、中期和远期网格单元,分别占42%、31%和27%。远期网格单元分布在宝应县中部和南部的平原区,该区域农田的连片性、细碎度和质量等别等优于其他区域。研究结果表明,该文提出的区域农田整治优先度评价方法,有助于确定农田整治先后顺序,明确优先开展整治区域和方向。该方法为区域土地整治规划提供支撑,也为中国各县市开展高标准基本农田建设提供科学参考。 |
