| 摘 要： | 西藏一江两河地区是经济快速发展地区,由于高寒和多风少雨,生态环境条件极其恶劣,景观系统抗御和修复干扰的能力微弱.因此,在该地区实施大农业开发工程不能走传统的开荒要粮的道路,而应实施农业景观调整规划,规划的重要内容有3项,即实施现代农业技术使现有的高产田改造成稳产高产田;使现有的大量中低产田改造成有灌排条件的高产田;选择干旱坡地、不平整土地和与当地农民生活相关不密切的旱地退耕还林还草.从而解决粮食需求问题,遏止生态环境急剧退化的趋势.

| Abstract: | The three rivers area is the rapid economic development area in Xizang. As the weather is frigid with frequent wind and little rain, the ecological environment condition in the area is extremely bad, and the resistance and rehabilitation ability of landscape system is weak. Therefore, in the implementation of agriculture development program in the area, it is advisable to adopt the traditional method of wasteland reclamation, instead, the a-griculture landscape in the area should be modified. The primary contents of the modification plan are implementing modern agricultural technology to improve the current fields with high yield to the fields with high and stable yield, improve the middle and low-yield fields to the high-yield fields with irrigation system and transform the dry land on the slopes, non-smooth land and dry land with non-importance to the residences' living to the forest land and grassland. So the problem of food demand will be solved and the degenerating trend of ecological environment will be controlled. |
