Patterns of Orchid Diversity and Their Potential Habitat Under Climate Change in Chongqing, China.

ABSTRACT: Global climate problems and the sharp decline in biodiversity have attracted widespread attention. Orchids, as the "flagship" species of biodiversity, are important indicators of ecological changes. This study took Chongqing as the study area and conducted a comprehensive survey of orchids through field investigation combined with data review to clarify Chongqing's diversity distribution pattern. The distribution of orchids was characterized by "high in the east and low in the west, high in the north and low in the south" horizontally. Vertically, the distribution was characterized by an obvious "unimodal distribution", with higher abundance in the low and middle altitude areas of 500-1499 m. The minimum temperature of the coldest month (Bio6), isothermality (Bio3), altitude (Bio20), and p
