寒冷指数 meaning in English

coldness index

Grey correlation analyses show that at the time axis , the factors influencing the diversity of plants strongly are primary productivity , annual precipitation , relative humidity , mean temperature in january , and potential evaporation etc . the spatial distribution pattern of terrestrial vertebrates including mammals , birds , reptilians and amphibians were studied with methods similar to those for plants . 7 d
通过d以排序表明， d以第一轴与多个环境因子均呈显著相关，其中与经度、年均温、年均降水量、年均相对湿度、潜在蒸发量、初级生产力呈正相关，与纬度、海拔、年均风速、寒冷指数、年均日照率呈负相关。
Meanwhile , we proved that the major factor that determines the distribution of plants in china is the primary productivity . the cold index ( the lowest temperature ) plays a more important role than the highest temperature and the annual mean temperature in restricting the diversity of plants
Dcca和cca排序也显示了和dca一致的结果，同时证明，决定中国陆地植物多样性分布格局的环境因素主要是初级生产力，而寒冷指数(即低温)对多样性的限制作用要大于高温和年均温的作用。
