摘　　要：为探讨辽宁泥质海岸杨树防护林对土壤物理性质的影响,在盘锦典型泥质海岸区域选取4种杨树纯林进行研究,结果表明:在0~20 cm土层,毛白杨防护林对土壤容重的改良效果最好,在20~40 cm土层,则是辽宁杨防护林改良效果最好;不同杨树防护林下土壤的总孔隙度以毛管孔隙度为主,非毛管孔隙度只占一小部分;0~20 cm土层的总孔隙度大小顺序是毛白杨>银中杨>辽宁杨>新疆杨,毛管孔隙度大小顺序是银中杨>辽宁杨>新疆杨>毛白杨,非毛管孔隙度大小顺序是毛白杨>银中杨>新疆杨>辽宁杨;20~40 cm土层的总孔隙度大小顺序是辽宁杨>新疆杨>银中杨>毛白杨,毛管孔隙度大小顺序是新疆杨>辽宁杨>银中杨>毛白杨,四种杨树防护林间的非毛管孔隙度差异不显著;0~20 cm土层的最大持水量大小顺序是毛白杨>银中杨>辽宁杨>新疆杨,毛管持水量大小顺序是毛白杨>银中杨>辽宁杨>新疆杨,田间持水量大小顺序是毛白杨>银中杨>新疆杨>辽宁杨;20~40 cm土层的最大持水量大小顺序是辽宁杨>新疆杨>银中杨>毛白杨,毛管持水量大小顺序是辽宁杨>新疆杨>银中杨>毛白杨,田间持水量大小顺序是新疆杨>辽宁杨>银中杨>毛白杨。In order to investigate the effects of Populus shelter forest on soil physical properties in nmddy coast of Liaoning Province, four species of Populus pure forest were selected for studyin the typical muddy coastal area of Panjim The results showed that the improvement effect of soil bulk densityof Populus tomeutosa shelter forest in 0 20 cm soil layer was the best. The 20 - 40 cm soil layer is the best improvement effect of Populus cctthayana Rehd. vat. cathayana shelter forest. The total porosity of the soil under different Populus shelter forests was dominated by the eapillaryporosity, and the non - eapillaryporosity only accounted for a small part. The order of the total porosity of 0 - 20 cm soil layer was Populus tomentosa 〉 Poplus alba ＂ Berolinensis＂ L 〉 Populus eathayana Rehd. vat. eathayana 〉 Populus alba vat. pyramidalis Bunge. The order of capillaryporosity was Poplus alba ＂Berolinensis＂ L 〉 Populus eathayana Rehd. vat. eathayana 〉 Populus alba vat. pyramidalis Bunge 〉 Populus tomentosa, and the order of non - capillary- porosity was Populus tomentosa 〉 Poplus alba Berolinensis＇ L 〉 Populus alba vat. pyramidalis Bunge 〉 Populus eathayana Rehd. vat. eathayana. The order of the total porosity in the 20 -40 cm soil layer was Populus eathayana Rehd. vat. eathayana 〉 Populus alba vat. pyramidalis Bunge 〉 Poplus alba Berolinensis＇L 〉 Populus tomentosa Carr. The order of capillary porosity was Populus alba vat. pyramidalis Bunge 〉 Populus eathayana Rehd. vat. eathayana 〉 Poplus alba Berolinensis＇L 〉 Populus tomentosa Carr. The difference in non - cap- illary porosity between the four shelterbelts was not significant. The order of maximum water holding capacity in the 0 - 20 cm soil layer was Populus tomentosa Carr 〉 Poplus alba Berolinensis＂ L 〉 Populus eathayana Rehd. vat. eathayana 〉 Populus alba vat. pyramidalis Bunge. The order of capillary water holding capacitywas Populus tomentosa Carr 〉 Poplus alba Berolinensis＂ L 〉 Populus eathayana Rehd. vat
