曾思齊 歐陽君祥 摘 要:根據(jù)馬尾松單木生長量模型,運用動態(tài)模擬方法,以Windows98為操作平臺,以VisualC++為開發(fā)工具,研制了馬尾松林撫育間伐的計算機決策系統(tǒng).系統(tǒng)可以根據(jù)用戶的需要,分別以林分最大蓄積量、最大生物量或最大貨幣收益為經(jīng)營目標(biāo),求解在各種間伐體制下各齡階的最適經(jīng)營密度.模擬結(jié)果表明:適時間伐明顯促進(jìn)了林分的生長,且立地質(zhì)量越好,間伐所產(chǎn)生效益越顯著.
Computer Decision-making System for Intermediate Cutting of Pinus massoniana Forest ZENG Si-qi(Central South
Forestry University, Zhuzhou 412006, Hunan, China) Abstract:Using the Windows 98 as the operating platform and the Visual C++ as the
software development kit, we developed a computer decisio n-making system for
intermediate cutting of Pinus massoniana based on the s ingle tree increment
model of Pinus massoniana with a dynamic simulated meth od. This system can help
you get the optical operating density of every age clas s of all kinds of
intermediate cuttings by setting the maximum amount of growing sto ck or the
maximum biomass or the maximum net income as the target of forest mana gement
according to the demand of users. The simulated results show that stan d grows
faster under proper cutting, and that the effects will be bette r under better
site conditions. |
