摘要
以四川省川南地区的内江市资中县,自贡市富顺县,宜宾市叙州区、长宁县、高县,泸州市古蔺县的马尾松(Pinus massoniana Lamb.)及其他主要人工林下的土壤为样本,通过土壤容重、土壤含水率、土壤总孔隙度、土壤密度、土壤有机质、土壤全氮、土壤全磷、土壤全钾共8项土壤理化数据的测定,对川南同一个区县内马尾松林与其他主要人工林的土壤理化性质进行了差异评价。结果表明:川南地区其他主要人工林与马尾松林相比较,林下土壤的4项物理性质无显著差异;林下土壤的4项化学性质,总体显著高于马尾松林,土壤有机质高出16.3%~129%,土壤全氮高出16.3%~223.4%,土壤全磷高出16.7%~65%,土壤全磷高出13.7%~46.7%。为此,提出了从土壤质量的角度出发,川南地区马尾松林改造为其他人工林是可行的。
In this study,soil samples of Pinus massoniana Lamb.,and other major artificial forests were collected in Zizhong County of Neijiang City,Fushun County of Zigong City,Xuzhou District of Yibin City,Changning County,Gao County,and Gulin County of Luzhou City in the southern part of Sichuan.Soil bulk density,soil moisture content,soil porosity,soil density,soil organic matter,soil total nitrogen,soil total phosphorus,and soil total potassium were determined.The difference in soil physical and chemical properties between Pinus massoniana forest and other major plantations in the same district and county in southern Sichuan was evaluated.The results showed that there were no significant differences in the four physical properties of soil under different afforestation types in Chuan Nan region.However,soil chemical properties under other major afforestation types were significantly higher than those under Pinus massoniana Lamb.forests.Soil organic matter was 16.3%~129%higher;soil total nitrogen was 16.3%~223.4%higher;soil total phosphorus was 16.7%~65%higher,and soil potassium was 13.7%~46.7%higher in soils under other afforestation types than those under Pinus massoniana Lamb.forests.Therefore,based on soil quality,it is feasible to transform Pinus massoniana Lamb.forests into other major afforestation types in the southern part of Sichuan.
