【摘要】：研究川牛膝在全國(guó)范圍的潛在分布及種植空缺,有利于為其實(shí)地保護(hù)及種植推廣工作提供依據(jù)。該文結(jié)合63個(gè)川牛膝地理分布數(shù)據(jù)和49個(gè)相關(guān)生態(tài)因子,利用3S技術(shù)及Max Ent模型對(duì)川牛膝在全國(guó)的潛在分布進(jìn)行預(yù)測(cè)及種植空缺分析。研究結(jié)果表明:(1)川牛膝在全國(guó)潛在分布面積約634 385.80 km2,主要分布于四川省的東北部、東南部,云南省的北部、東南部,貴州省的西部、西南部,重慶市的西南部、東北部,陜西省的西南部,甘肅省的東南部,湖北省的西部,廣西省的西部,西藏自治區(qū)的東南部等區(qū)域;(2)影響川牛膝生長(zhǎng)的主要生態(tài)因子是降水量、海拔、最冷月極低溫度、土壤類(lèi)型、月均溫等;(3)全國(guó)川牛膝種植空缺區(qū)域主要位于四川省廣元市、綿陽(yáng)市、雅安市、樂(lè)山市、涼山州、攀枝花市,陜西省漢中市,云南省大理自治州、怒江自治州、楚雄自治州、保山市、曲靖市、文山自治州,貴州省黔西南自治州等。該研究結(jié)果對(duì)掌握川牛膝的生長(zhǎng)環(huán)境、預(yù)測(cè)在全國(guó)的潛在分布及其栽培推廣具有重要意義。
[Abstract]:The study on the potential distribution and planting vacancy of Achyranthes bidentata in the whole country is helpful to provide the basis for the field protection and planting popularization. This paper combines 63 geographical distribution data of Achyranthes bidentata and 49 related ecological factors. Using 3s technique and Max Ent model, the potential distribution of Achyranthes bidentata in China was predicted and the planting vacancy was analyzed. The results show that the potential distribution area of Achyranthes bidentata in China is about 634,385.80 km2, mainly in the northeast and southeast of Sichuan Province. Northern, southeast, western, southwest, southwest, southwest of Chongqing, northeast of Chongqing, southwest of Shaanxi Province, southeast of Gansu Province, west of Hubei Province, west of Guangxi Province, The main ecological factors affecting the growth of Achyranthes bidentata are precipitation, altitude, coldest month, extremely low temperature, soil type, monthly mean temperature, etc.) the vacancy area of cultivated Achyranthes bidentata in Sichuan Province is mainly located in Guangyuan City, Sichuan Province. Mianyang City, Ya'an City, Leshan City, Liangshan Prefecture, Panzhihua City, Hanzhong City, Shaanxi Province, Dali Autonomous Prefecture, Yunnan Province, Nujiang Autonomous Prefecture, Chuxiong Autonomous Prefecture, Baoshan City, Qujing City, Wenshan Autonomous Prefecture, The results of this study are of great significance in understanding the growth environment of Achyranthes bidentata and predicting its potential distribution in China and its cultivation and popularization.
