摘要
为了了解龙岩烟区植烟土壤pH的时间和空间分布情况,本文采用传统统计学和地统计学相结合的方式,进行了龙岩烟区植烟土壤pH的时空变异研究。结果表明:1982、2001、2011年龙岩烟区植烟土壤pH分别为5.34、5.03、5.23,土壤酸化得到有效抑制;1982、2001、2011年土壤pH半方差函数模型分别为线性模型、线性模型、指数模型。空间分布上,1982、2001、2011年高值区域分别呈现块状、点状、块状;不适宜种植烤烟的地区呈现先上升后下降的趋势,最适宜区面积减少。
The spatial and temporal variation of pH value of tobacco-growing soil in Longyan tobacco-growing areas was studied by the combination of traditional statistics and geostatistics. pH values of tobacco planting soil in Longyan tobacco-growing areas in 1982, 2001 and 2011 was 5.34, 5.03 and 5.23, respectively, meaning soil acidification was effectively inhibited. The semi-variance function model of soil pH in 1982, 2001 and 2011 was a linear model, linear model and exponential model correspondingly. In terms of spatial distribution, the high-value areas in 1982, 2001 and 2011 was in the form of block, dot and block accordingly. The areas that are not suitable for growing flue-cured tobacco show a trend of increasing first and then decreasing, and the area of the most suitable area is reduced.
