摘要: <正>用9种外生菌根菌对4种杨树苗木进行了菌根化试验,比较了各外生菌根菌与不同杨树形成菌根的能力以及不同接菌方法下的菌根感染率,并探讨了外生菌根菌对杨树苗木生长的影响。结果表明:红绒盖牛肝菌Xc、美味牛肝菌Be、彩色豆马勃Pt和紫金蜡蘑La均能与杨树苗木较好地形成菌根,Xc在4种杨树苗上的菌根形成能力强于其他菌根菌,Be在I-69杨上形成菌根能力较强,Pt和La则形成能力较弱;褐环乳牛肝菌Sl、褐疣柄牛肝菌Ls、华美牛肝菌Bs、头状秃马勃Cc和黄须腹Rl在灭菌基质上不易与杨树形成外生菌根,但在自然土中却可形成;通过打孔接菌的方法,苗木菌根化率要比移栽时施底肥接菌和蘸根法接菌时高,其操作也更简便、省工;小叶杨可与大多数供试菌根菌形成菌根,I-72和NL-351杨则与Pt的亲和度最高,I-69杨与Xc菌的亲和度最高。研究显示,与I-69杨、I-72杨和NL-351杨最适的外生菌根菌分别为Be、Xc和Pt;与小叶杨最适的外生菌根菌为Xc和Be;这些菌根菌对苗木的促生效果显著。

Abstract: Zijinshan Mountain national forest park is selected as a case study area. Remote sensing and GIS software Erdas 8.7, ArcGis 9.0 are employed as the spatial platforms of doing scenario planning. Three different periods remote sensing data in the years of 2000 (IKNOS)、2002 (SPOT5) and 2004 (QuickBird) are used to do the supervised classification and neighborhood analysis to build three scenarios of scenic forest in ten years. After comparisons of the three scenarios from two aspects of landscape spatial pattern and protection goals, an optimized planning plan is made. Results show that, compared with the landscape pattern of 2002, farm land disappears completely in optimized planning plan. The proportion of broadleaved forest, industry and management land, land for touring service facility decreases by 18.48%, 2.30%, 2.85% respectively. The conifers, gardens, mixed forest increase by 13.26%, 14.81%, 4.47% respectively. The scenic beauty grade of scenic forest in winter is improved, the multiple goals of landscape tourism, forest cultivation, supplying entertainment places for local residents, biodiversity conservation can be met at the same time. Thus the theoretical basis for sustainable management plan of scenic forest is put forward.
