a regulation show a certain regularity. The aboveground biomass is increasing as the increase of altitude until which reaches 701850m, where owns the biggest biomass value, after different slope aspect is not so far different from each other. The biomass value of each slope gradient is arranged from high to low : slight slope, ramp, flat slope, abrupt slope .Through test, Grey system prediction and Markov prediction model are respectively suitable for biomass density prediction of different forest type and area prediction. Forest area, above ground biomass, biomass density of Jingouling forest farm are respectively hm2, , t/ hm2.【關(guān)鍵詞】森林資源清查資料 森林地上生物量 時(shí)空動態(tài)變化 生物量預(yù)測 生物量時(shí)空動態(tài)分析系統(tǒng)【英文關(guān)鍵詞】Forest inventory data Forest aboveground biomass Spatial and temporal change Biomass prediction Biomass temporal and spatial analysis system【目錄】金溝嶺林場森林地上生物量時(shí)空動態(tài)分析與預(yù)測摘要57Abstract78第一章 緒論1526 引言1516 國內(nèi)外研究現(xiàn)狀及發(fā)展趨勢1624 森林生物量計(jì)量方法和估算1619 森林生物量時(shí)空動態(tài)研究進(jìn)展1921 森林生物量趨勢預(yù)測研究進(jìn)展2124
