摘要
生态脆弱区兼有生态保护和经济发展双重压力,退耕还林工程在生态脆弱区改善自然环境、调节区域气候、促进农户增收和推进区域经济发展等方面发挥重要作用。该文以辽西低山丘陵区为例,对3种国家地理标志保护产品生态经济林的营造技术和综合效益进行比较分析,结果表明,山杏适合荒山荒地低成本造林绿化,大枣适合退耕还林地块和立地条件较好的荒山配套造林,核桃对立地条件要求最高,需要较高的林间管理技术和病虫害防治技术。
Ecologically fragile areas face the dual pressures of ecological protection and economic development. The Conversion of Cropland to Forest Project plays an important role in improving the natural environment,regulating regional climate,promoting farmers’ income and promoting regional economic development in ecologically fragile areas.Taking the lowhills area of western Liaoning as an example,this paper made a comparative analysis on the construction technology and comprehensive benefits of three kinds of eco-economic forests protected by national geographical indications. The results indicated that: Prunus sibirica is suitable for lowcost afforestation in wasteland,Zizyphus jujuba is suitable for afforestation in the land retuned from farmland or wasteland with good site conditions,and Juglans regia has the highest requirement on site conditions,which required higher forest management technology and pest control technology.
