摘要
在对山东省黑松海防林进行全面踏查的基础上 ,应用典型调查和定位观测相结合的方法 ,开展了沙质岸黑松海防林的调查研究。采用数量化理论Ⅰ的方法 ,对黑松海防林立地质量进行了数量化评价 ,划分出1 1种立地类型 ;并采用系统聚类法 ,将研究区的黑松海防林划分为 3种林分生长类型。其中生长类型Ⅰ的林分生长表现最好 ,生长类型Ⅱ的次之 ,生长类型Ⅲ的最差。在综合分析黑松海防林防护成熟和数量成熟的基础上 ,提出黑松海防林的防护成熟期 :生长类型Ⅰ为 1 5～ 5 7a,生长类型Ⅱ为 1 4～ 3 2a,生长类型Ⅲ为 1 3～ 2 8a;确定黑松海防林的更新期 :生长类型Ⅰ为 3 3～ 5 7a,生长类型Ⅱ为 2 3～ 3 2a ,生长类型Ⅲ为 2 1～ 2 8a;确定黑松海防林的合理更新年龄 :生长类型Ⅰ为 3 3a,生长类型Ⅱ为 3 2a ,生长类型Ⅲ为 2
Based on the overall on-the-spot survey, combined the typical investigation and fixed position measurement, the coastal protection forest of Pinus thunbergii in Shandong Province was studied. The site conditions of the coastal protection forest were evaluated by means of the quantitative theory I and divided into 11 types, then classified the stand into three height classes by systematic cluster analysis. The results showed that the tree height for class Ⅰis the highest, classⅡis medium and the classⅢ is the lowest. Then based on the comprehensive analysis of the protection maturity and quantitative maturity, the protective maturity period(PMP)of the coastal protection forest for classⅠto Ⅲ were 15～57 a, 14～32 a, and 13～28 a respectively, the regeneration period(RP)were 33～57 a, 23～32 a and 21～28 a respectively, and the reasonable regeneration age(RA)were 33 a, 32 a,and 28 a respectively.
