黄河下游丘陵地区人工林土壤养分与水文特征差异
Variations in Soil Nutrients and Hydrological Characteristics of Plantation Forests in the Hilly Area of the Lower Yellow River Basin
摘要
Abstract
This study examines how different types of plantations(pure and mixed forests)affect soil hydrological proper-ties and nutrient status in the hilly region of South-central Shandong,located in the lower Yellow River Basin.The goal is to provide a scientific basis for optimizing the management of soil and water conservation forests.Five typical planta-tion forest types were selected:Quercus acutissima pure forest(ML),Robinia pseudoacacia pure forest(CH),Pinus tabuliformis pure forest(YS),broad-leaved mixed forest(KYH:Q.acutissima×R.pseudoacacia),and coniferous-broadleaved mixed forest(ZKH:P.tabuliformis×Q.acutissima).Through field sampling and laboratory analysis,sev-eral soil indicators were systematically measured,including bulk density,porosity,water-holding capacity,pH,organic carbon,nitrogen,phosphorus,and potassium.The results indicated that the Robinia pseudoacacia pure forest had the highest soil water-holding capacity(field capacity of 52.6%)and high porosity,but poor soil aeration.In contrast,the Pinus tabuliformis pure forest demonstrated lower levels of aeration and water-holding capacity.Mixed forests showed a more balanced performance between water retention and aeration,with the coniferous-broadleaved mixed forest showing a water-holding capacity close to that of the Robinia pseudoacacia pure forest.In terms of nutrients,the broad-leaved mixed forest significantly outperformed the pure forests,with levels of organic carbon(27.58 g·kg-1),total nitrogen(4.76 g·kg-1),and available nutrients.Overall,mixed forests,particularly broad-leaved mixed forest,exhibited supe-rior soil functions regarding the balance between water retention and aeration as well as nutrient supply.Therefore,mixed afforestation models are recommended for ecological restoration in this region to achieve the dual goals of soil and water conservation and the enhancement of soil fertility.关键词
