中文摘要	通过野外土壤剖面调查和采集土壤样品,对比研究5种植被恢复模式(侧柏纯林、枫香+侧柏林、枫香纯林、湿地松+枫香林、湿地松纯林)下土壤理化性质,探讨不同植被恢复模式对邵阳县喀斯特地区土壤理化性质的影响.研究结果表明:5种植被恢复模式中侧柏纯林、枫香+侧柏混交林以及枫香纯林呈碱性,而湿地松+枫香混交林以及湿地松纯林生长速度快,7年生的湿地松平均胸径7.79 cm,平均高5.07 m,土壤呈酸性;土壤含水率较低,并相差不大,其中上坡位的枫香纯林土壤含水率最小,只有18.11%;土壤质量密度从大到小的顺序为:侧柏纯林、枫香纯林、湿地松+枫香混交林、湿地松纯林、侧柏+枫香混交林,土壤孔隙度则相反.土壤全P、全K、全Ca、全Mg、全Fe、Zn、Cd、速效N和速效K的含量在不同植被恢复模式中差异显著(P<0.05),其中,土壤有机质和土壤全Ca的含量差异最为明显;不同植被恢复模式中的土壤全N、Cu、Mn、速效P的含量差异不显著,只与土壤的本底值有关.
英文摘要	In order to study effects of different patterns of vegetation restoration on soil physical-chemical properties in rocky desertification area, 5 patterns of vegetation restoration stand were chosen in Shaoyang County, Hunan province, which were Platycladus orientails (Linn.) Franco Pure Forest (POPF), Liquidamba formosana Hance and Platycladus orientails (Linn.) Franco Mixed Forest (LPMF), Liquidamba formosana Hance Pure Forest (LFMF),Pinus elliottii pure forest (PEPF), Pinus elliottii and Liquidamba formosana Hanee Mixed Forest (PLMF). Soil physical-chemical properties in the 5 patterns of vegetation restoration in rocky desertification area were studied by using soil profile survey methodology. The results show a clear pH differentia, which was a weak acidity in both PEPF and PLMF while a weak alkalic in the other three patterns of vegetation restoration, indicated that the accumulation of acids secreted by Pinus elliottii resulted from its fast growing (7 years old forest with average DBH of 7.79 cm and average height of 5.07 m) is now effecting the pH of soil and other species in the community. The moisture content seemed to be not easy to change for the plants, which was all very low in the study area, and the lowest soil moisture content was in the uphill in LFPF with the value of 18.11%. The order of soil bulk density from high to low was: POPF, LFMF, PLMF, PEPF, LPMF, but the order of soil porosities was on the contrary, which demonstrated a less returning of litter in pure stand. There were significant differences among the 5 patterns of vegetation restoration stand in total P, K, Ca, Mg, Fe, and Zn, Cd and available N and K; and the most significant differences were taken place between the soil organic matter and soil total Ca. But there were no significant differences among the 5 patterns of vegetation restoration stand in total N, Cu and Mn, which had only related to the soil background value.
