摘要:

粮食生产地域功能具有显著的空间异质性和时间变异性。深入开展区域粮食生产地域功能的评价分级及动态变化研究有助于强化县域粮食生产功能、保障粮食安全和提高农民收入。本文以环渤海地区327个县域为研究单元,通过构建粮食生产功能指数及考核模型,计算了1990和2007年的指数并分析其变动规律。结果表明:粮食生产地域功能一级区主要分布在辽宁中部平原的北部,太行山山前平原区、海河冲积平原区县域的粮食生产功能次之,山地丘陵区、坝上高原区及人口稠密的市辖区等的粮食生产功能弱。环渤海地区各县粮食生产功能总体呈上升趋势,平原区县域粮食生产功能位显著提高,退耕还林还草等政策实施使山地丘陵区的粮食生产功能逐渐降低,市辖区及周边市县的粮食生产功能位快速下降。基于指数的评价分析,结合区域粮食总产量和区域发展定位,将研究区划分为国家级商品粮基地区、省级商品粮基地区、地级市商品粮基地区、一般粮食产区等4个类型区。依据各县域的粮食生产功能定位,进一步探讨强化县域粮食生产功能与优化生产要素配置的财政转移支付、区域经济补偿、政绩考核等创新机制和政策。

Abstract:

Territorial function of grain production in various regions has a significant spatial heterogeneity and temporal variability. To strengthen the function of grain production at county-levels, to ensure national grain security and to improve farmers' income, it is of great practical significance to conduct a deep evaluation and classification research on grain production function. Taking the 327 counties in the area along Bohai rim as the research units, this paper constructs an evaluation index system for grain production function and an index analysis model, to evaluate and grade the functions of grain production in 1990 and 2007. The result demonstrates that grain-oriented functional areas are mainly distributed in the northern part of the plain area in central Liaoning province. The grain production function of counties in the piedmont plain of Taihang mountain and alluvial plain region of Haihe river takes the second place. The counties in mountainous-hilly areas, tableland areas and densely populated city areas, have weak grain production function. On the whole, the grain production function showed an increasing tendency from the year 1990 to 2007. The function of grain production has been improved significantly in plain areas and has been weakened as the implementation of Conversion of Cropland to Forest and Grassland Project in mountainous-hilly areas. It has been shown a strong downward trend in cities and their surrounding counties as the sharp reduction of cultivated lands and the swift growth of regional population. Moreover, based on grain function index and its dynamic changes, combined with the regional total grain production and regional development orientations, the research regions fall into four types: national commodity grain base, provincial commodity grain base, city commodity grain base and general grain producing region. Finally, this paper explores the innovation mechanisms and favorable policies to enhance the grain production function of each county and to optimize the allocation of production factors, including the financial transfer payment, regional economic compensation, and government performance assessment, which provide a scientific guidance for coordinated development and sustainable growth of farmers' income.
