渭北旱塬降水对农作物生长适宜度的模糊分析
- Title:
- FUZZY ANALYSIS THE SUITABLE DEGREES OF THE PRECIPITATION TO THE AGRO-CROPS GROWING IN TEH ARID PLAIN OF NORTHERN WEI RIVER
- Keywords:
- arid plateau of the Northern Wei River; pxecipitation resource; suitable degree of crop growth; fuzzy analysis
- 摘要:
- 根据模糊集理论，从“适量”、“适时”和“有效程度”三个指标出发，就渭北旱塬地区降水资源对农作物生长发育的影响提出了一种数学模型，并根据计算结果和参照有关资料进行了模糊聚类分区。结果表明，它较好地反映了本区降水资源的地域特征，为该地区一些主要农作物的合理布局提供了科学依据和准确信息。
- Abstract:
- This paper is based on the theory of fuzzy, and start from the three indexes which of suitable quantity, timely and effective degree to evaluate and analysis the effect of the precipitation resource to the agro-crops growing and get a model for effectiveness of the precipitation resource; The results of calculation show that it fairly good reflects the regional features of the precipitation resources in this area, and give scientific and accurate data for the rational distribution of the main agricultural crops.
