山区反季节蔬菜生产气候适宜性研究

Climatic Adaptability of Inverse-seasonal Vegetable Growth in Mountain Area

通过对农业生态气候适宜度概念、原理和方法的研究,在众多资料的基础上,建立了高山反季蔬菜光、热、水、湿隶属函数,并对其全生育期进行动态模拟。根据模拟出的各生态适宜度指标计算结果,总结出了所研究区域高山反季蔬菜生产气候资源的分布规律,以及安全生产高度和适宜播期的确定方法,可为高山反季节蔬菜产业的健康发展提供参考。

On the basis of research on the conception, principle and method of agro-ciimatic ad-aptability, the fuzzy subjective-degree function on sunshine hour, temperature, precipitation and humidity were established with the meteorological data of 42 years, the DEM data in 1：250000 scale and the vegetable data of investigation. Then the processes were simulated through the vegetable growth. According to the results of various agro -climatic adaptability indices, the distribution rule of agro -climatic resourees of vegetable growth and the means to confirm the growing height without risk, and fitting date of seeding in the regions were given. These can provide useful references for promoting healthy development of inverse-seasonal vegetable growing in mountain area.
