鄂西山地退耕还林模式探讨

Discussion on Model of Conversion of Cropland to Forest in Mountainous Land of Western Hubei

摘要:

鄂西山区是湖北省先期开展退耕还林试点工作的主要区域,通过深入调查研究与科学论证,提出了陡坡退耕地生态林治理、中山坡地水保林治理、坡耕地栽植生物埂治理、坡耕地林草间作治理、低山丘陵河谷生态林治理5种适合鄂西山地生态建设的典型生态治理模式。同时,分析了各种模式的特点、技术方案及适应范围。

Abstract:

The mountainous area in the west of Hubei is main area that launches pilot work of conversion of cropland to forest in Hubei. Under investigations and scientific appraisal, five kinds of eco-treatment models were built: eco-forest treatment model of steep cultivated land, the soil and water conservation forest treatment model of mid-mountain slop, biological hedge treatment of slope land, forest-herbage intercropping treatment of slope land, eco-forest treatment model in lower hill and river-valley. Meanwhile, these treatment models were analyzed with the characteristic, technological scheme, and accommodation.
