摘　　要：文中给出生态空间、生态场、红松种群生态场的定义,分析了由单株母树繁衍而成的红松后代的时空分布,并依据其分布特性给出了以个体数量u和密度ρ为标度的红松种群数量场的函数描述。函数刻画了非均匀场的空间分布特征,在此基础上进一步讨论了非均匀场形成的生态机理及生态场研究的经济意义。In this paper,we have given the definations of the ecological space 0,the ecological field and the eclogical field of the Korean pine family,analyze the distribution of a Korean pine propeny propagated by a Koreanpine seed in the ccological space D,and according to the characteristicsof the distrbution with the individual puantities U and density E beingscalar degrees,we giver the function description of the quantity field ofthe Korean pine family.This function describes the characteristics ofspace distrbution of non-homogeneous field,base on it,the ecologicalfunction which the non-bomogeneous field forms and the economical meaningof ecological field study are discussed.
