| 中文摘要: |
| 以植被重建后的科尔沁沙地为研究对象，采用野外采样与实验室检测分析相结合的方法，对其
南缘樟子松固沙林采伐迹地上的更新树种林下土壤特性演变特征进行研究，运用模糊综合评判法，选用7
项评价指标对植被重建后土壤肥力特征进行综合评价。结果表明，植被重建后，土壤肥力各指标均有所提
高，其中五角枫林地有机质、全氮、速效钾增幅最大，红刺榆林地碱解氮、全钾增幅最大，彰武松、樟子松
林地全磷、有效磷增幅最大；4种植被重建类型对土壤肥力的综合改良效果为五角枫（0.8735）＞彰武松
（0.6494）＞红刺榆（0.5618）＞樟子松（0.4814），该评价结果可为当地植被恢复提供一定参考。 |
| 英文摘要: |
| Horqin sandy land after vegetation restoration was selected as the research object，by using the
field sampling investigation and laboratory testing method，the evolution characteristics of soil properties under
the regeneration trees，which located in the Pinus sylvestris var. Mongolica forest of the south edge of Horqin sandy
land，were studied. According to the fuzzy comprehensive evaluation，the soil organic matter，total nitrogen，total
phosphor，total potassium，alkaline nitrogen，available phosphorus and available potassium were select to evaluate
the soil fertility quality after vegetation restoration. The results showed that all the soil fertility indexes improved after
vegetation restoration. The increment in soil organic matter，total nitrogen and available potassium of Acer mono，
the increment in alkaline nitrogen and total potassium of Hemiptelea davidii and the increment in total soil phosphor，
available phosphorus of P. densiflora and P. sylvestris was the maximum. The effect of comprehensive improvement of
soil fertility for 4 types of vegetation restoration was in the order of A. mono（0.8735）> P. densiflora（0.6494）> H.
davidii（0.5618）> P. sylvestris（0.4814）. This result will provide scientific basis for the local ecological restoration. |
