2.1 技术简介

技术定义:

The comprehensive measures including interplanting & intercropping are applied in the small watershed to control soil and water loss and improve integrated production.

2.2 技术的详细说明

说明:

Based on the national conditions and soil and water loss in the area, the corresponding SWC measures were adopted to pursue the targets including: 1. Closing the hilly and mountain area of 224ha for the timber forest and grass growing as well as preventing soil and water loss; 2. Adjusting the land use structure so as to strengthen the comprehensive development of the hilly land as well as crop land irrigation; 3. Changing the area of W & S loss to economic vegetation land; 4. Constructing reservoirs and roads.

3.2 应用该技术的当前土地利用类型

注释:

Major land use problems (compiler’s opinion): The layout of vegetation is not rational. The traffic is not convenient.

Major land use problems (land users’ perception): Lack of new species and SWC technique. Hopefully more funds could be supported from government.

Grazingland comments: Reclaiming fish pools area of 5.6 ha, stall breeding chicken, duck etc.

Problems / comments regarding forest use: Planting young bamboo in the sparse woodland (about 135 ha) in the western watershed and planting lotus after deforesting the woodland (36.7 ha) in the southwestern watershed as well as changing the adult tea gardens to afforest in the northeast watershed.

Forest products and services: timber, grazing / browsing, nature conservation / protection


Type of grazing system comments: Reclaiming fish pools area of 5.6 ha, stall breeding chicken, duck etc.
