石屏小白得林区云南松工程造林成效初析

概述了石屏小白得林区云南松工程造林地的自然条件，工程造林实施的技术措施；通过工程实施资料和固定样地监测材料，对小自得林区云南松工程造林的成效进行了分析。经成效分析得出工程造林质量高，幼林生长迅速、丰产、优质。6年生云南松林分每公顷的蓄积量为32．922m3，是一般造林最好林分的1．1倍，总体设计预测值的2．04倍。预测其经济效益显著，同时也取得显著的社会和生态效益。为速生丰产优质的云南松用材林基地建设起到了示范作用。

Preliminary Analysis on the Effects of Engineering Afforestation with Pinus yunnanensis in Xiaobaide Forest District of Shipin

The paper has summarized the natural conditions and the technical measures taken in engineering afforestation with Pinus yunnanensis in Xiaobaide forest district of Shipin.? Furthermore, it has analyzed the effects of the afforestation on the base of information implemented in the afforestation and material got from monitoring on the fixed sample plots.? The analysis draws conclusions that engineering afforestation is of high quality and young forests are of fast growing, high yield and superior quality.?The volume per hectare of 6 years old stand is 32 922m 2, which is 1 1 times of normal stand, 2 04 times of predict value overall designed.? It is forecast that the engineering afforestation of Pinus yunnanensis will achieve not only great economic effects, but also social and ecological effects as well, which has demonstrated for timber base establishment of Pinus yunnanensis forests of fast growing, high yield and superior quality.?
