摘　　要：土壤是植物赖以生存的物质基础,是生态安全和绿地健康的重要载体。济南是座依黄河而居的城市,滨河生态系统的土壤肥力是济南绿化体系服务功能的核心生态因子之一。本文对济南市黄河风貌带的16处公园的表层土(0~30 cm)和深层土(30~60 cm)采集了268个土壤样品,分别测定容重、pH、EC、有机质、水解性氮、有效磷和速效钾7项指标。然后用修正的内梅罗综合指数法对土壤肥力进行了评价。重点区域的土壤肥力指数P为0.67,定级为贫瘠。为黄河淤背区因地制宜的改良土壤,适地适树种植植物提供了技术对策。Soil is the material foundation on which plants rely for survival,and an important carrier for ecological security and green space health.Jinan is a city located along the Yellow River,and the soil fertility of the riverside ecosystem is a core ecological factor for Jinan's greening system.This article collected 268 soil samples from the surface soil(0-30 cm)and deep soil(30-60 cm)of 16 parks located in the Yellow River landscape belt of Jinan City.Seven indicators,including bulk density,pH,EC,organic matter,hydrolysable nitrogen,available phosphorus,and available potassium,were measured.Then,the revised Nemero comprehensive index method was used to evaluate soil fertility.The soil fertility index P of the key areas was 0.67,classified as poor.This provides technical solutions for improving soil quality and planting plants in the Yellow River siltation area according to local conditions.
