摘  要:
运用MaxEnt生境预测模型,结合地理信息系统ArcGIS 9.3,根据鸭儿芹当前的分布数据和12个环境变量,预测了鸭儿芹在我国各省区栽培的气候适应情况。结果表明:鸭儿芹在浙江栽培的气候适宜性综合指数为54.53,其次为湖南(50.47)、江西(48.96);鸭儿芹也能够在广西、贵州、安徽、上海和福建等地栽培,气候性综合指数为40.09~45.88;鸭儿芹在广东、重庆、江苏、中国台湾、陕西、云南、四川和我国香港的栽培适应能力相对较低,综合指数为24.26~36.72;在河南、甘肃、山东、山西和西藏等省地区,只能在局部地区进行鸭儿芹栽培推广;河北、海南、辽宁、内蒙古、北京、吉林、天津、新疆、青海、黑龙江等地不具有鸭儿芹栽培的气候条件。某一地区的最热季度平均雨量、最冷和最干季度平均温度以及最湿季度平均温度对栽培推广鸭儿芹有重要影响。

摘  要:
According to the current data of Cryptotaenia japonica distribution and 12environmental variables the climatic adaptation of this wild vegetable,to different areas of China was predicted by means of the maximum entropy algorithm modeling program(MaxEnt)and the geographical information system ArcGIS 9.3.The results showed that the 3 highest composite climatic adaptability indexes of cultivating C.japonica in China are 54.53 in Zhejiang Province,50.47 in Hunan Province and 48.96 in Jiangxi Province.Also C.japonica can be cultivated in Guangxi,Guizhou,Anhui,Shanghai and Fujian regions,and those regions' composite climatic adaptability indices are 40.09-45.88.The composite climatic adaptability indices of cultivating C.japonica in Guangdong,Chongqing,Jiangsu,Taiwan,Shanxi,Yunnan,Sichuan and Hong Kong regions are relatively low,being 24.26-36.72.In Henan,Gansu,Shandong,Shanxi and Xizang regions,only some areas are suitable for cultivating C.japonica,but Hebei,Hainan,Liaoning,Inner Mongolia,Beijing,Jilin,Tianjin,Xinjiang,Qinghai and Heilongjiang regions have no climate conditions of cultivating C.japonica.The important factors influencing successful cultivation of C.japonica are the average rainfall of the hottest season and the average temperatures of the coldest,driest and wettest seasons in an area.
