- W3025672185 abstract "To master the soil fertility situation of afforestation areas, where trees would be planted, the soil samples of 524 afforestation areas were taken to test its nutrients in six prefectures of Tibet, and the soil fertility was analyzed by the method of modified Nemerow synthesis index. The results showed that the synthetic fertility index of afforestation areas was between 0.425 and 1.972 in Tibet. The numbers of afforestation areas with general level, barren level, and fecund level occupied 65.9%, 34.9% and 0.2%, respectively. The mean fertility index of each soil property was in the order of alkalytic nitrogen＞ pH ＞ total nitrogen ＞ available potassium ＞ organic matter ＞ available phosphorus ＞ total phosphorus ＞ total potassium, which was between 0.654 and 2.643. The fertility level of total nitrogen, alkalytic nitrogen was mostly at the fecund and very fecund level. That of available potassium, organic matter, and total phosphorus was mainly at the general level. That of available phosphorus and total potassium was mainly at barren level, and soil pH was at a proper level. The synthetic fertility index in different prefectures was in the order of Nyingchi ＞ Qamdo ＞ Shannan ＞ Lhasa ＞ Shigatse ＞ Ngari, which of afforestation areas was at the barren level in Ngari, Shigatse and Lhasa. The synthetic fertility index of Qamdo and Nyingchi were at general level. The number of afforestation areas at general level or barren level was nearly same in Shannan. The soil fertility of afforestation areas was low in Tibet as a whole. The soil synthetic fertility and sub-fertility of soil properties became gradually good from the northwest (Ngari) to the southeast (Nyingchi), suggesting obvious horizontal zonality.为了掌握西藏将要造林作业区的土壤肥力水平,对6个地市524个造林作业区的土壤样本进行了养分测定,采用改进的内梅罗综合指数法分析土壤肥力水平.结果表明: 西藏造林作业区土壤综合肥力指数为0.425～1.972,土壤综合肥力水平一般的作业区数量占64.9%,贫瘠的占34.9%,肥沃的占0.2%.各属性分肥力指数均值表现为: 碱解氮>pH>全氮>速效钾>有机质>有效磷>全磷>全钾,指数值为0.654～2.643,全氮、碱解氮的肥力水平主要为肥沃、很肥沃,速效钾、有机质、全磷的肥力水平主要为一般,有效磷、全钾的肥力水平主要为贫瘠,土壤酸碱度适宜.各地市造林作业区平均土壤综合肥力指数表现为: 林芝市>昌都市>山南市>拉萨市>日喀则市>阿里地区,其中,阿里地区、日喀则市、拉萨市造林作业区土壤综合肥力水平为贫瘠,昌都市、林芝市为一般,而山南市一般和贫瘠的数量相当.西藏造林作业区土壤综合肥力水平总体偏低,土壤综合肥力、土壤各属性肥力水平由西北部的阿里地区至东南部的林芝市逐渐趋好,具有明显的水平地带性规律." @default.
