广东省农用地产能空间分异特征研究

Spatial differentiation characteristics of agricultural land productivity in Guangdong province

应用空间插值模型和探索性空间数据分析方法,对广东省各二级区农用地产能的空间分异特征进行了分析,探讨了广东省农用地产能与人均GDP的空间关联特征,为区域农业发展提供对策和建议。结果表明:广东省农用地产能受耕地空间格局影响显著,农用地理论单产与可实现单产受农用地自然质量的影响明显,人均GDP与农用地产能的空间关联性具有差异性,广东省二级区人均GDP与农用地产能的空间关联性由高到低依次为粤东沿海地区和雷州半岛中部>粤中南地区和粤北地区>粤西南地区和潮汕平原区>珠三角平原区。

The paper studies the spatial differentiation characteristics of agricultural land productivity of the second farmland district in Guangdong province. Through spatial modeling and interpolation, the authors explore the relation between agricultural land productivity and GDP in order to provide scientific support for decision-making of land policy. The result indicates that the agricultural land productivity in Guangdong province is significantly affected by the cultivated land spatial distribution patterns; the theoretical and actual yield of farmland are largely determined by land quality; the correlation between GDP per capita and farm land productivity is different in space. The order of correlation between GDP per capita and agricultural land productivity of the second farmland district in Guangdong province from high to low is in the following： the eastern coastal area and central of Leizhou peninsula, the south central area and the north area, the southwest area and Chaoshan plain area, and Pearl River plains area.
