【摘要】：通過野外取樣實(shí)測和基于ArcGIS軟件的地統(tǒng)計(jì)學(xué)分析空間插值方法對(duì)石河子墾區(qū)18個(gè)農(nóng)牧團(tuán)場(莫索灣、下野地、安集海、石河子)土壤有效硅(SiO_2)及其空間分布狀況進(jìn)行調(diào)查分析,并研究土壤機(jī)械組成、有機(jī)質(zhì)、全氮、全磷、及pH等理化指標(biāo)對(duì)土壤有效硅影響的關(guān)系。結(jié)果表明:石河子墾區(qū)耕層0~20cm土壤有效硅處于較豐富水平,平均質(zhì)量分?jǐn)?shù)為313.3mg·kg-1。受"高山-綠洲-沙漠"山盆結(jié)構(gòu)地形地貌影響,石河子墾區(qū)有效硅空間分布存在明顯不均衡性,整體呈現(xiàn)東南高而西北較低的特點(diǎn)。4個(gè)灌區(qū)土壤有效硅平均質(zhì)量分?jǐn)?shù)順序?yàn)?石河子安集海莫索灣下野地。墾區(qū)土壤pH為7.58~9.11,在此范圍內(nèi)有效硅隨pH增加而明顯降低。墾區(qū)土壤有效硅顯著受土壤粘粒影響,并隨土壤粘粒的增加而升高(r=0.291,P0.01)。土壤有效硅與土壤肥力因素中的有機(jī)質(zhì)和全磷呈極顯著正相關(guān),但與土壤全氮相關(guān)性不明顯�？梢�,土壤有效硅與土壤pH、粘粒、有機(jī)質(zhì)、全磷緊密相關(guān)。
[Abstract]:The spatial distribution of soil available silicon sio _ 2 in 18 farm farms (Moso Bay, Lower Field, Anji Sea, Shihezi) in Shihezi Reclamation area was investigated by field sampling and spatial interpolation method based on geostatistics analysis based on ArcGIS software. The effects of physical and chemical indexes such as soil mechanical composition, organic matter, total nitrogen, total phosphorus and pH on soil available silicon were studied. The results showed that the available silicon in 0~20cm soil was abundant in Shihezi reclamation area, and the average mass fraction of available silicon was 313.3mg kg-1. The spatial distribution of available silicon in Shihezi Reclamation area is obviously unbalanced due to the topography and landform of the mountain basin structure of "Alpine Oasis Desert". The order of the average mass fraction of available silicon in the four irrigated areas is as follows: lower Mosuo Bay, Anji Bay, Shihezi. The soil pH was 7.58 ~ 9.11, and the available silicon decreased with the increase of pH. Soil available silicon was significantly affected by soil clay and increased with the increase of soil clay. Soil available silicon was positively correlated with organic matter and total phosphorus in soil fertility factors, but not with soil total nitrogen. It can be seen that soil available silicon is closely related to soil pH, clay, organic matter and total phosphorus.
