摘要:

该文运用文献资料、因素分层指标、GIS空间插值等方法，以河南省为研究对象，将中低产田改造和土地整理项目相结合，分析了中低产田综合整理的内涵和分区整治要点； 选择标准粮产量、等指数和土壤肥力3个因素10个指标，构建了中低产田划分标准。在河南省粮食主产区划分了3个一级整理类型区和9个二级整理类型区，并按分区制订了9种工程技术模式并提出各自组合特征。研究结论：（1）河南省高、中、低产田面积比重约为49%、31%、20%，高产田集中在黄淮海平原区，低产田分布在豫西、豫南的山地丘陵区，中产田交叉分布在二者之间； （2）以工程为组合，按灌排方式、田块形式、生物多样性等差异，提出了中低产田分区综合整理的重点和措施，为打造河南省粮食核心区战略提供技术支撑。

Abstract:

Middle and low-yield field has become a constraint for food production to a new level. To implement the comprehensive improvement of middle and low-yield field is the key to increase grain production. By using literature, stratification index, GIS spatial interpolation methods, taking Henan Province as the research object, combined transformation of middle and low-yield field and land consolidation project, this paper analyzed the connotation and key points of comprehensive improvement in middle and low-yield field and zoning improvement, established the classification standard of middle and low-yield field by selecting ten indicators and three factors, such as the standard grain yield, grade index and soil fertility In the main grain producing areas in Henan Province, it divided there Level 1 remediation type areas and nine Level 2 remediation type areas, developed nine kinds of engineering modes and their features. The conclusions were that (1) The proportion of area for high, medium and low-yield fields was about 49%, 31% and 20% in Henan, the high-yield field mainly distributed in Huang-Huai-Hai Plain, while the low-yield fields distributed in Mountainous and hilly region of West Henan and the mountainous region of Southern Henan Hilly Region. The middle field distributed cross the two kinds of areas; (2) some measures for the comprehensive improvement of middle and low-yield field were put forward in terms of irrigation and drainage ways, terraces form, biodiversity, etc, which can provide technical support for the implementation of remediation projects and to build the grain core area strategy in Henan province.
