Analysis of Forest Resource Change and Forecast of Forest Ecological Index in the Implementation of Natural forest Protection Project in Yichun Forest Management Bureau

伊春林区所处的地理位置和生态环境独特,是东北地区陆地生态系统的主体之一。森林茂密的小兴安岭承担着抵御西伯利亚寒流,阻挡西太平洋热浪,防御蒙古高原沙尘的功能;对东北亚地区气温、湿度和降水具有调节功能,保障了这一地区的生态安全和经济社会可持续发展;对于保护全球生物多样性具有重要作用,是动植物资源活基因库,尤其为珍稀濒危物种提供了天然庇护所和繁衍地。现介绍伊春在实施天保工程一期、二期以来资源变化情况,并对未来森林生态指标做了前景预测。

Due to the unique geographical location of Yichun forest and ecological environment, is one of the main terrestrial ecosystems in Northeast China. The wooded small Xingan mountains bear against the cold in Siberia, blocking the Western Pacific heatwave, the defense of Mongolia plateau dust, the temperature of the Northeast Asian region, humidity and precipitation has the function of regulation, guarantee the a regional ecological security and sustainable economic and social development. It plays an important role in global biodiversity conservation function, is a live gene pool of animal and plant resources, especially provide a natural shelter and reproduction for the protection of rare and endangered species in Yichun. The article mainly introduces the implementation of natural forest protection project period, resources change two since the period, and the future of forest ecological index forecast.
