延边州可利用农林生物质能资源现状调查与评价

Investigation and Evaluation of Available Status of Agricultural and Forestry Biomass Energy Resources in Yanbian Prefecture

摘要:

延边朝鲜族自治州位于吉林省东部的中朝边境，辖区面积 4.27 万 km，人口约 214.6 万人，全州林地面积 354.13 万 hm。在农林生物质能资源调查过程中，按照保守性和前瞻性原则，通过文案调查、座谈调查、入户调查和实地调查，对汪清县及延边州其他 7 个县 (市) 的农林生物质能资源进行了调查与评价。经调查，延边州地区农林业生物质能年理论资源量为 367.04 万 t，延边州地区农林业生物质能年可供应量 91.73 万 t。

Abstract:

Yanbian Korean Autonomous Prefecture is located on the border between China and North Korea in the east of Jilin Province. It has an area of 42 700square kilometers, a population of about 2.146 million people, and a forest area of 3.541 3 million hectarec. According to the principles of conservation and forward - looking, we studied the agricultural and forestry biomass of Wangqing County and other 7 counties(cities)in Yanbian Prefecture by investigating and evaluating copy investigation, panel surveys, household surveys, field surveys, and energy resources during the process of investigating the biomass energy resources of agriculture and forestry. Based on the investigation, the theoretical amount of biomass energy for agriculture and forestry in Yanbian Prefecture is 3.670 4 million tons, and the annual availability of biomass energy for agriculture and forestry in Yanbian Prefecture is 917 300 tons.
