Abstract

[Objectives] To calculate and study the biomass emergy of main forests in Shangri-La, Tibetan area of Yunnan Province. [Methods] Four main forest biomass values of P. likiangensis and A. georgei, P. densata, Q. aquifolioides and P. yunnanensis in Shangri-La, Yunnan were determined by emergy method. [Results] The energy of the four kinds of forests was 2 572 252.490 6×106 J, the emergy was 10 767.336 6×1020sej, and the economic value was 43 756.841 1×0.1 billion yuan. The total economic value was 41.56 times of GDP and 5 494.94 times of forestry output value in 2020; the emergy storage density was 9 271.795 9×1010 sej/m2, and the per capita emergy reserve was 741.2 202×1016 sej/person; the per capita macro value was 30.122 081 million yuan, which was 875.59 times that of the per capita GNP of 34 402 yuan in 2020. [Conclusions] The value of forest ecological assets was mainly distributed in P. likiangensis and A. georgei in four main forests and arborous layer in vertical layer. The value of forest biomass in Shangri-La is much higher than that of developing forestry economy, and it is a valuable and potential asset. We should strengthen the protection of forest ecological environment and maintain forest assets.
