【摘要】：運(yùn)用高精度南方NTS-960R型免棱鏡全站儀,結(jié)合多邊形樣地森林資源調(diào)查方法,對(duì)赤峰市旺業(yè)甸林場(chǎng)200塊標(biāo)準(zhǔn)地進(jìn)行調(diào)查。選取4塊有代表性的標(biāo)準(zhǔn)地,對(duì)標(biāo)準(zhǔn)地每木進(jìn)行胸徑和樹高測(cè)量,將多邊形樣地法數(shù)據(jù)與樣地每木檢尺數(shù)據(jù)比較分析。結(jié)果表明:多邊形樣地法調(diào)查面積和調(diào)查株數(shù)不固定,每個(gè)樣地的面積在0.005~0.015 hm2,樹木6~9棵,外業(yè)工作量相對(duì)于標(biāo)準(zhǔn)樣地法小;多邊形樣地法在天然林和混交林中的精度低,在單層林和人工林中的精度高;隨著樣地?cái)?shù)量增加,精度逐漸提高,在天然林中,精度可達(dá)到85%以上,可適用于二類調(diào)查;在人工林中,精度可達(dá)到95%以上,可適用于三類調(diào)查。將多邊形樣地進(jìn)行固定,可實(shí)時(shí)對(duì)林分生長(zhǎng)量進(jìn)行監(jiān)測(cè)。
[Abstract]:Based on the high precision NTS- 960R prism free total station and the investigation method of polygons forest resources, 200 standard plots of Wangye Dian Forest Farm in Chifeng City were investigated. Four representative standard sites were selected to measure the DBH and tree height per wood in the standard land, and the polygonal sample plot data were compared with the data of each wood scale in the sample plot. The results showed that the area and number of plants investigated by polygonal plot method were not fixed, and the area of each sample plot was 0.005 鈮，
