黑龙江狗枣猕猴桃资源地理分布与气候水热关系分析
Analysis of the geographical distribution of Actinidia kolomikta resources in Heilongjiang Province and its relationship with climatic hydrothermal factors
摘要
Abstract
To explore the geographical distribution pattern of Actinidia kolomikta in Heilongjiang Province and the key climatic factors affecting its distribution,this study conducted field surveys and data inquiries.Based on 15 climatic and hydrothermal indicators from different distribution sites,we analyzed the geographical distribution pattern of A.kolomikta and its relationship with climatic hydrothermal indicators.The limiting climatic factors affecting the geographical distribution of A.kolomikta in Heilongjiang Province were determined through principal component analysis.The results showed that the horizontal distribution range of A.kolomikta in Heilongjiang Province is between 127°28′E and 134°05′E,and between 43°05′N and 48°40′N.It is vertically distributed at an altitude of 200 to 1,200 meters,with a concentration in the area of 400 to 800 meters.The wide range of extreme and optimal values for various climatic and hydrothermal indicators indicates the broad ecological adaptability and strong cold tolerance of A.kolomikta resources.Principal component analysis showed that the climatic hydrothermal condi-tions affecting the distribution of A.kolomikta in Heilongjiang Province were low temperature,high temperature,and humidity,with January average temperature,annual average temperature,extreme low temperature,and annual precipitation being the key climatic factors.These research results will provide a reference for the genetic diversity,domestication and cultivation,and protection and utilization of A.kolomikta resources in Heilongjiang Province.关键词
