| 摘 要： | 对青海大通县浅山区和脑山区退耕还林不同配置模式生态服务功能进行了综合评价。结果表明,在浅山区,模式C(青杨+枸杞)为最优配置模式,综合评价得分231.12,各种配置模式综合评价得分排序为:模式C(青杨+枸杞)>模式A(川赤芍)>模式D(中国沙棘)>模式B(紫花苜蓿)>模式E(柠条);在脑山区,模式F(青海云杉)为最优配置模式,其综合评价得分250.54,各种配置模式综合评价得分排序为:模式F(青海云杉)>模式G(华北落叶松)>模式J(青杨+中国沙棘)>模式H(白桦+青海云杉)>模式K(青海云杉+中国沙棘)。综合考虑生态服务功能及环境特点,在浅山区阴坡推广应用模式C,阳坡推广应用模式A;在脑山区阴坡推广模式F,阳坡推广模式J。 |

| Abstract: | The paper focused on the synthetic evaluation on each ecology service function of conversion cropland to forest in Datong county,Qinghai.The results showed that in the shallow mountainous areas,pattern C was the best disposition pattern,the synthetic evaluation of which scored 231.12,and the arrangement order of each disposition pattern according to their synthetic evaluation scores was pattern C(Populus cathayana Lycium barbarum) > pattern A(Paeonia veitchii) > pattern D(Hippophae rhamnoides ssp.sinensis) > pattern B(Medicago sativa) > pattern E(Caragana korshinskii);while in the brain mountainous areas,disposition pattern F is the best one,the integrated evaluation of which scored 250.54,and the arrangement order according to their synthetic evaluation scores was pattern F(Picea crassifolia) > pattern G(Larix principis-rupprechii) > pattern J(Populus cathayana Hippophae rhamnoides ssp.sinensis) > pattern H(Betula latyphylla Picea crassifolia) > pattern K(Picea crassifolia Hippophae rhamnoides ssp.sinensis).Therefore,in terms of the ecology service function and environmental characteristics,the conclusion can be drawn that in the low-hill areas,pattern C should be applied in the northern slope and pattern A in the southern slope;while in the remote-hill areas,pattern F should be applied in the northern slope and pattern J in the southern slope. |
