吉兰泰盐湖引种樟子松的试验研究

STUDY ON THE INTRODUCING EXPERIMENT OF PINUS SYLVESTRIS IN JILANTAI SALT LAKE

本文通过对吉兰泰地区樟子松引种及生长状况调查，运用主成份分析法，找出该区评价樟子松生长的第一主成份、第二主成份，并运用 Ｒ 型因子分析法将其生长指标归类：地径、树高为一类，冠幅为一类；分析了灌水、施肥等人为经营措施对樟子松生长的影响；对照比较了樟子松林地改善后的林地环境。从而初步论证了在吉兰泰地区干旱、土壤严重盐渍化内陆盐湖地区引种樟子松的可行性。

Evaluation on the First main composition and the seconel main composition of Pinus sylvestris growing were found out throngh the study of growing situation of introduced pinus sylvestris in Jilantai and by analysis methocl of main composition.Growth index were classified wtilizing R factor analysis method,that is .Ground Diameter and stand height are is one classification,scope of crown is another classification. By analying growth stability of Pinus sylvestris in Jilantai,by contrasting growing situation of Pinus sylvestris in fowr different degree of salinizeal area,and analysisy manage menourement such as shrub and fertilization etc,exerting upon growing situation of Pinus sylvestris,and by contrasting improved forest land enviorment of Pinus sylvestris ,primaryly demonstrated the feasibility of introducing Pinus sylvestris on the arid and scverely salinized interion salt lake area in Jilantai.
