研究了不同植物在石质山地的造林成活率、土壤化学性质随造林年限的变化和造林措施对土壤化学性质和植物胸径、树高年净生长量的影响。结果表明：不同植物在石质山地的成活率在21%～85%之间,其中白榆和沙打旺的成活率分别为81%和85%,而小叶杨、刺槐、栾树的成活率均在70%左右;植被能明显提高石质山地不同土层的有机质、全N、P2O5含量,但提高程度随土层深度、养分种类和造林年限的不同而不同;在同一土层,生物复合肥料、菌剂和保水剂均显著提高土壤有机质含量（p〈0.01）并显著降低土壤P2O5含量（p〈0.01）;只有保水剂可引起土壤全K含量的明显升高;生物复合肥料、菌剂和保水剂均显著提高白榆、小叶杨、刺槐、栾树树高和胸径的年净生长量,但保水剂的提高程度最高。

The survival rate of forestation, the change of soil chemical properties with the planting years, and the in- fluence of planting measures on soil chemical properties and the annual net growth of dbh and tree height have been studied for different plants in rocky mountain. The results show that the survival rates of different plants in rocky mountain are from 21% to 85% , and the survival rates of Ulmus pumila and Astragalus adsurgens are 81% and 85% seperaterly, and the survival rates of Populus simonii, Robinia~pseudoacacia and Koelreuteria paniculata are a- bout 70%. The vegetation can improve the content of organic matter, total nitrogen and P2Os, which the increasing degree is different with the different soil depth, nutrient varieties and planting years. In the same layer, bio - com- pound fertilizer, inocula and water retaining agent can increase the content of organic matter (p 〈 0. 01 ) and de- crease the content of PzO5 ( p 〈 0. 01 ) obviously. Only water retaining agent can increase the content of total potas- sium obviously. The bio - compound fertilizer, inocula and water retaining agent can obviously increase the annual net growth of dbh and tree height of Populus simonii, Robinia pseudoacacia and Koelreuteria paniculata, which the water retaining agent has the highest improvement.
