研究区域位于云南省东北部会泽县城东郊的头塘小流域，属金沙江支流牛栏江水系上游。以自然植被针叶混交林地为参照，与针叶人工纯林地、阔叶人工纯林地、针叶人工混交林地进行比较，分析不同植被类型土壤物理性状的差异和动态过程，以及土壤物理特性变化与人为干预影响之间的关系。结果表明，阔叶林和混交林对土壤性状的恢复作用大于纯林，华山松对土壤环境的恢复作用大于云南松，且与林龄正相关。
研究區域位于雲南省東北部會澤縣城東郊的頭塘小流域，屬金沙江支流牛欄江水繫上遊。以自然植被針葉混交林地為參照，與針葉人工純林地、闊葉人工純林地、針葉人工混交林地進行比較，分析不同植被類型土壤物理性狀的差異和動態過程，以及土壤物理特性變化與人為榦預影響之間的關繫。結果錶明，闊葉林和混交林對土壤性狀的恢複作用大于純林，華山鬆對土壤環境的恢複作用大于雲南鬆，且與林齡正相關。

The study area is located in Toutang small watershed , Huize in the northeast of Yunnan , which belongs to upstream of Niulan River , a tributary of Jinsha River system .Taking natural vegetation of coniferous forest land as a reference , compared with artificial pure coniferous woodland , artificial pure broadleaf woodland , artificial mixed coniferous land , the differences in soil physical properties and dy-namic process of different vegetation types , as well as the relationship between human intervention and changes of the soil physical characteristics were analyzed .The results showed that the role of broadleaf mixed forests in soil properties restoration was greater than pure forest , the role of Pinus armandi in the soil environment restoration was greater than Yunnan pine , and positively correlated with stand age .
