以千岛湖景观林改造为研究对象，采用影子工程法、费用分析法和Shannon-Wiener指数法评估景观林改造的理论生态价值。结果表明：景观林改造不仅改变马尾松单色纯林的现状，增强了景区的观赏性，其生态服务功能价值也发生了变化，其中增值的有7项，分别是多样性保育、保肥、调节水量、净化水质、释氧、固碳和固土功能价值；降低的有2项，分别是滞尘和吸收SO2功能。特别是涵养水源量功能增值达0.52万元· hm-2· a-1，仅蓄水能力就增加637.45万t· a-1，相当于建造6个库容100万m3的水库。

Taking the scenic forest transformation of Qiandao Lake as the study object ,the theoretical ecological value of the Scenic Shannon-Wiener Index.The results showed that the scenic forest transformation not only changed the monocolor and pure forest for Pinus massoniana ,but also enhanced the scenic ornamental value , as well as changed the ecological service value ,seven of which in-creased,they were the diversity nursing ,conserving manure ,regulating water flow ,water purification , oxygen release ,carbon seques-tration and soil fixation function value;two of which decreased ,they were the holding dust ,absorbing SO 2 function.The water conser-vation quantity function incresead 5200 RMB· hm-2 · a-1.The water-holding capacity increased 6374500 t· a-1 ,equivalently to be 6 reservoirs with the capacity of 1 million m3 water.
