为了解桉树复合经营林-药模式的生态经济效益,并筛选出同时具备较好生态效益和经济效益的优良模式,以桉树纯林为对照,连续5年对桉树人工林间种药材(扶芳藤、金银花和鸡骨草)的6种模式进行对比和观测研究。结果表明:(1)6种模式中A1和A3模式具有较好的生态效益。对比CK模式,A1和A3的枯落物量分别增加了19.5%和30%;蓄积量分别增加了25.18 m3/hm2和36.39 m3/hm2;林分空气和土壤温度明显下降,湿度有所提升;土壤孔隙度和最大含水量明显提高,有机质和速效N、P、K含量提高3.5%以上;地表径流降低9.2%以上。(2)A3和B3模式具有较好的经济效益,药材净收益率分别为94.10%和185.16%;总净收益率分别是CK模式的102.2%和86.5%。(3)A3模式同时具备良好的生态效益和经济效益,适宜推广应用。
Study on ecology and economy beneift of Eucalyptus and medical plant intercropping models of Eucalyptus plantation
To study the ecological and economic benefits on Eucalyptus and medical plant intercropping mode, and choose a good pattern both have good ecological beneifts and economic beneifts. This paper studied on tree and medical plant intercropping mode (including Euonymus fortunei and Lonicera japonica and Abrus cantoniensis) of Eucalyptus plantation for 5 years, which compared with pure forest of eucalyptus mode. The results showed:(1) Compared with CK patterns, A1 and A3 of the six kinds of models had good ecological beneifts. The amount of litterfall increased by 19.5 percent and 30percent, The volum increased by 25.18m3/hm2 and. 36.39m3/hm2, Forest air and soil temperature decreased obviously, the humidity was improved, soil porosity and the maximum water content increased Obviously, the organic matter and available N, P, K content increased by more than 3.5 percent, the Surface runoff reduced by more than 9.2 percent. (2) The A3 and B3 model has good economic beneifts, the net yield of medicine was 94.1 percent and 185.16 percent, It’s total net yield is 102.2 percent and 86.5 percent of the CK mode. (3)the A3 mode both have good ecological beneift and economic beneift,and it is suitable for popularization and application.
