摘  要:
用土壤微形态的研究方法观察分析了黄河三角洲土壤的微观特征,用以研究土壤的抗蚀性。研究结果表明该区土壤发育处于初始阶段,土壤在矿物成分、有机物质、土壤形成物等方面仍然在很大程度上保留着冲积物的特征。土壤微结构差,抗蚀性弱,微生态系统脆弱,土壤经人为扰动后易发生水土流失。由三角洲顶部向河口地区,土壤发育愈来愈差,也愈容易遭受侵蚀。因而土地开发利用中,必须重视对土壤微生态环境的保护。

摘  要:
By the micromorphological investigation, the microcharacteristics of soil are analysed. The purpose is to study the erosion durability of the soil. The results show that soil development in the Yellow River delta region is in the initial stage and the soil maintains the peculiarities of alluvial deposit in some aspects, including mineral composition, organic substance and pedological features. The soil microstructure is poor and the erosion durability is not good. The microecological system is vulnerable. The soil and water loss takes place easily after artificial disturbance. From the top of the delta to Hekou, soil development comes to a lower quality and soil erosion is easier to appear. As is shown, the more attention should be paid to the protection of the soil microecoenvironment.
