摘要
青海省生态环境恶化的主要特征是 :草地退化 ,水土流失 ,土地沙化 ,冰川湿地退缩 ,自然灾害频繁 ,人畜饮水困难 ,农村能源短缺。当前生态环境治理面临着试验示范不够、缺少治理规划、种苗供应混乱、资金投入不够等问题 ,需要加强治理规划工作和技术支撑体系、建立生态环境治理责任制、紧密结合生产结构调整及草产业的发展等方面开展工作。需要依据草业科学的原理 ,在生态环境治理中重视生态工程设计的应用 ,对治理区按照草地农业系统四个生产层次统筹考虑优化生产结构 ,发挥各系统和层次间的耦合效应。生态环境治理面临的问题为草业科学原理的实践及发展提供了广阔的天地。
Grassland degeneration, soid and water loss, land desert, shrinking back of glacier and swamp, frequently natural disasters, difficulty of using water for human and animals and deficiency of rural energy, were the basic features of worsened eco environment of Qinghai province. Deficiencies in demonstration and experiment, shortage of harnessing plan and funds, and confusion of seeds supplying, were main problems we must face now. Some works like control planning, setting up the technology suport system, establishing responsibility, and closely combining the agricultural structure adjust ment and the development of prataculture must be strengthened. When we carried out the control of eco environment, we must base on the principle of pratacultural science, devote much attention to the applying of eco engineering design, and to the policy of overall consideration and all round arrangement that in view of 4 production layers of agro grassland system. So, we can optimize the industrial stucture and get a coupling effect from every system and layer. To solve the problems that existed in process of eco environment control, practice and development of pratacultural principle could get a vast world.
