黑龙江省玉米的生态适宜性评价及种植区划

基于生态适宜性评价的基本理论，利用GIS技术、模糊数学等方法，通过对研究区玉米生理生态特性与环境关系的分析，筛选出生态适应性评价指标，构建生态适宜性评价模型，研究黑龙江省玉米生产的合理布局。结果表明，在黑龙江省适宜种植玉米的区域主要分布在齐齐哈尔市、绥化地区、哈尔滨的部分县(市)以及松花江沿线的县(市)，总面积达172 300 km²，占研究区总面积的31.88%。

Ecological Adaptability Evaluation and Planting Division of Maize in Heilongjiang Province

Based on the theory of ecological adaptability evaluation, GIS technology, fuzzy mathematics and so other methods were used through studying the relationship between ecophysiological features and environment, selecting evaluating indexes of ecological adaptability and constructing evaluation model. The result showed that maize was suitable in the large areas in the whole province. The most suitable areas were 172 300 km² and occupied 31.88% of the whole province, which included Qiqihar, Suihua, Harbin and the cities along the Songhua river. This study maybe provide an objective and flexibility reference for regional adjustment of planting structure and optimization of planting pattern.
