摘要：

为了研究蔬菜生长与气候资源的适宜情况，利用浦东25年以月为基础的气象数据，结合蔬菜的生物学特性，根据农业生态气候适宜度理论，用模糊数学的方法，确立温度、光照、水分3个方面的隶属函数及综合评价模型，并利用该模型逐月对蔬菜生长的气候适宜度进行评价。结果表明，蔬菜生长适宜性随全年各气候单因素的变化而变化；不同权重气候单因素配合情况影响对蔬菜生长适宜程度的综合评价；可以获得相应的栽培管理方法，以保证蔬菜在相对适宜的条件下良好生长。本研究结果填补了蔬菜生长气候适宜性模糊评价的空白，可为蔬菜四季均衡生产提供科学依据。

Abstract:

In order to investigate the suitability degree between the growth of vegetables and climatic resources, based on the biological characteristics of vegetable and the 1975-2009 meteorological data in Pudong District, combined the theory of suitability-degree of agro-ecological climate resources, by using fuzzy mathematics, the author established climate suitability degree models of 3 climatic factors and comprehensive evaluation models to evaluate the suitability of vegetable growth by month. The results showed that the suitability of vegetable growth changed with the change of climatic factors, the coordination of the climatic factors with different weights affected the comprehensive evaluation of the suitability of vegetable growth, the research got the corresponding method of cultivation and management to ensure that the vegetables grew well under the relative suitable conditions. The study filled in a gap of fuzzy evaluation to the suitability of vegetable growth, and could provide theoretical foundation for the scientific year-round production of vegetable.growth by month. The study can provide theoretical foundation for the scientific year-round
