洛阳市森林生态系统服务功能物质量和价值量评估
Evaluation of Forest Ecosystem Service Material Quantity and Value of Luoyang
摘要
Abstract
As a main part of the terrestrial ecosystem,forest plays an important ecological service function.Based on the data of forest management inventory of Luoyang conducted in 2018,this study evaluated the forest ecosystem service functions in Luoyang according to the national standard"Specifications for Assessment of Forest Ecosystem Services"(GB/T 38582-2020).The results showed that the amount of soil conservation in the forest ecosystem of Luoyang was 3.21 × 107 t/a,the amount of forest nutrient retention was 8.52×104 t/a,water conservation was 6.64×108 m3/a,carbon fixation was 2.03X106 t/a,oxygen release was 2.37× 106 t/a,the amount of negative ion produced was 1.07×1026/a,amount of pollu-ted gases absorbed was 8.49X104 t/a,and dust retention was 9.50X 106 t/a.The forest ecosystem service value of Luoyang in 2018 was 284.76 billion yuan,and the values of various service functions ranked as wa-ter conservation＞biodiversity protection＞carbon fixation and oxygen release＞soil conservation＞atmos-pheric purification＞nutrient retention＞forest recreation.The spatial distribution of material quantity and value of forest ecosystem service functions all generally showed the pattern of southwest＞central＞north-east.The forest ecosystem service function value of the counties of Song County,Luanchuan and Luoning County in the southwest accounted for 68.73％of the total,while the forest ecosystem service function val-ue of the urban area of Luoyang,Yichuan County,Mengjin District and Yanshi District in the northeast accounted for 6.35％of the total.The service values of different forest types ranked in the order of arbor forest＞shrub forest＞economic forest＞bam boo forest.The arbor forests service value was 240.78 billion yuan per year,accounting for 87.98％of the total.The service values of different dominant tree species ranked as Quercus＞Robinia pseudoacacia＞Populus＞other hardwoods＞Pinus tabuliformis＞Cupressus funebris＞Paulownia＞mixed coniferous and broadleaf forests＞other softwoods＞mixed broadleaf fo-rests＞Larix gm elinii＞other coniferous forests.关键词
