基于DTOPSIS法评价唐山北部山区板栗栽培气象条件

Evaluation of Meteorological Conditions on Planting Chestnut in Tangshan Northern Mountain Area Based on DTOPSIS Method

为了探讨唐山北部山区不同地方板栗栽培的气象条件特征,根据板栗生长周期对气候条件的要求,结合板栗生长特点和果树专家的思想,采用DTOPSIS分析法对唐山北部地区板栗生长适宜性的气象条件进行了综合优势评价。评价结果表明:从气候角度分析,唐山市北部各县(市、区)并非都适宜板栗生长,最适宜的地方当属北部山区的迁西县,其次是迁安,滦县、遵化、丰润和玉田则不适宜。

In order to explore meteorological conditions characteristics of chestnut cultivation in northern mountainous places of Tangshan,according to climate requirements of chestnut growth cycle,combined with chestnut growth characteristics and ideas of fruit-tree experts;evaluation of comprehensive advantages on chestnut growth in northern Tangshan mountain area was made using DTOPSIS method.Results showed that there was not suitable to plant chestnut in all Tangshan northern countries(cities,districts)from the climate perspective.Qianxi town was the most suitable place to plant chestnut,secondly Qian′an,then Luanxian and Zunhua.It was unfit to plant chestnut in Zunhua,Fengrun and Yutian.
