摘要

粮食安全是区域发展的长期战略问题，在人口激增，耕地面积减少趋势得不到有效抑制的客观背景下，提高粮食生产效率成为提高粮食生产量的关键。基于DEA Malmquist模型和ESDA技术，结合地理学研究中的空间格局分析方法，测算了我国粮食重点区河北省1990-2005年138个县的粮食生产效率，重点讨论了大尺度上县级层次近15 a来粮食生产效率空间聚集格局演化特征与规律。研究结果表明，研究期内河北省县级粮食生产效率存在空间聚集分布格局，粮食生产效率区际间的差异有所减小;各项粮食生产效率指数局部空间聚集格局显著，空间聚集格局演化规律明显。该项研究成果可从方法论上为定量测算粮食生产效率和空间格局特征提供借鉴，同时丰富粮食生产与耕地保护研究内容，为科学合理确定粮食生产功能分区，制定区域粮食安全战略提供重要的参考依据。

Abstract

Food security is a strategic concern of long-term regional development.Given the rapid population growth and continuing reduction in arable lands

increasing food production efficiency becomes the key to increase food production.Using the ESDA techniques and DEA Malmquist model

in conjunction with the spatial pattern of geographical research methods

we estimated grain production efficiency of 138 counties in Hebei Province from 1990 to 2005

and discussed the evolution characteristics and patterns of spatial clustering of the grain production efficiency on the county-level in Hebei Province.Results showed that grain production efficiency of 138 counties were aggregated spatially in the provincial region; however

the inter-regional differences were reduced.The local spatial aggregation pattern of grain production efficiency indices were significant

and the evolution of spatial aggregation pattern were evident on county-level in Hebei Province from 1990-2005.This study provides methodology for estimating spatial patterns of production efficiency

scientific basis for properly regionalizing production

and regional strategy for food security.
