摘要
在近期昆明市森林资源规划设计调查成果资料基础上进行补充调查,从坡度和土壤厚度2方面对昆明市林地立地质量状况进行分析.结果表明:全市立地质量较好的林地资源占全市林业用地面积的58.22%,适宜发展商品林;其余的41.78%为立地质量较差的林地资源,主导利用方向为以防护为主的公益林.林分质量分析结果,昆明市各林分立地条件类型单位面积蓄积量的大小反映了不同立地质量林地的林木生长水平差异.建议根据林地立地质量和林分质量进行合理布局,制定昆明市林业产业发展规划.
A supplementary survey has recently been done on the basis of obtained data from forest resource planning and design of Kunming city, and forestland site quality has also been analyzed from 2 aspects of soil thickness and gradient. As a result, forestland resource with better site quality accounts for 58.22% of total forestland area of the whole city, suitable for commercial forest, while the rest accounting for 41.78% is poor site quality toward non-commercial forest. In term of stand quality, the stock volume per unit area of all stand site conditions reflects woods＇ difference in growth on different quality lands. The paper suggests formulating a rational plan for forestry industry development according to site condition and stand quality.
