It embodied that the content ofsoil organic matter increased, soilunitweight improved, and the number ofsoil microorganism increased.
具体表现在增加了土壤有机质含量，有利于土壤容重的改善，同时增加了土壤微生物种群和数量。

The effects of high intensity fires on soilunitweight, porosity and separate coefficient were significant.
高强度火烧对土壤容重、孔隙度和分散系数的影响均显著。

However, the difference ofsoil moisture increase with the soil depth among 4 mulching materials. All mulching can decrease soil unitweight. And straw mulching has the most effects.
