摘要
针对以林场基础建立的森林公园普遍存在的森林景观不够丰富的问题,就森林公园森林景观提质改造进行探讨,通过对杉木纯林与杉木林下空地套种木荷两种林分生长因子进行对比分析,结果表明,混交林的阔叶树生长良好、杉木阔叶树混交林的杉木各项生长因子增幅较大,平均胸径、平均单株材积、林分总蓄积量分别比杉木纯林有所增加,混交林的总持水量增大,0cm^20cm土层土壤水分显著提高,森林景观有较大改善。
Aiming at the common problem of insufficient forest landscape in forest parks built on the basis of forest farms,the improvement and transformation of forest landscape in forest parks were discussed.The results showed that the broadleaf grew well,the growth factors of Cunninghamia lanceolate increased greatly,the average DBH,the average volume of individual tree and the total volume of stand increased,the total water holding capacity of mixed forest increased,the soil moisture of 0 cm^20 cm soil layer increased significantly.The forest landscape has been greatly improved.
