摘要 針對云南省鮮切花產業不斷發展壯大與鮮切花價格難以預測的矛盾,擬設計基于智能算法的影響鮮切花價格因素的智能驗證模型:根據實際需求將政策指導矩陣進行修改完善,確定市場競爭力最強、市場前景最好的鮮切花品種;然后,基于昆明國際花卉拍賣交易中心官網提供的數據分析框定影響因素;最后,以月季鮮切花為例,采用GRNN神經網絡算法構建影響鮮切價格因素的驗證模型,確定鮮切花價格的影響因素。該驗證模型的建立為構建鮮切花價格預測模型提供了智力支持。

Abstract Aiming at the contradiction between the continuous growth and development of fresh cut flowers industry and the price of fresh cut flowers in Yunnan Province,based on intelligent algorithm,an intelligent verification model of fresh cut flowers price factor was designed.According to the actual demand,the policy guidance matrix was improved to determine the best market competitiveness and the best market prospect of fresh cut flowers.Then,based on the data provided by official website of Kunming International Flower Auction and Trading Center,the influencing factors were analyzed.Finally,taking the fresh cut flowers of rose as an example,the GRNN neural network algorithm was used to construct a verification model affecting the price factors of fresh cut flowers,to determine the influencing factors of the price of fresh cut flowers .The establishment of the validation model provided intelligence support for constructing the price prediction model of fresh cut flowers.

云南省高原氣候顯著,晝夜溫差大,海拔差距大,使得其省內鮮切花產量高、色彩鮮艷、品種多樣,云南省鮮切花現已成為全國乃至全亞洲的高原特色產物之一。云南省鮮切花銷量占全國銷量的70%左右,特別是寒冬季節,鮮切花呈現供不應求的態勢。目前,云南省大力發展高原農業特色產業,鮮切花成為重點發展產業之一。隨著鮮切花產量的不斷增長,中國花卉協會、園林網等網站也曝出了特定時段鮮切花滯銷的新聞。在供不應求與嚴重滯銷等復雜環境的綜合影響下,鮮切花在不同時期的價格預測就顯得尤為重要,特別是影響鮮切花的價格因素成為影響云南省鮮切花產業的重點因素。因此,對影響鮮切花價格因素進行研究刻不容緩。……
