摘要
四川是中国生态环境保护和建设的重点地区。在 2 0世纪 80年代初期 ,科学家提出四川要发展生态农业 ,生态农业才是农业发展的方向。原始森林减少 ,生态功能削弱 ,土地荒漠化和水土流失面积大 ,不合理的资源开发和建设加速水土流失 ,城市生活垃圾和工业废弃物、酸雨、农药、化肥过量使用、农用薄膜的残留、畜禽粪尿污染是四川农业生态环境存在的主要问题。改善四川农业生态环境的对策是大力保护天然林 ,退耕还林还草 ;加强农业生态环境保护和治理 ,强化生态农业工程建设 ;启动农业清洁生产工程 ;重视生态农业技术创新。大力发展生态农业科技产业 ,以构筑生态安全体系为根基 ,以公司加农户的产业运营模式 ,以信息技术的有机整合 ,有力推进生态农业的科技产业模式。
Sichuan is an important area of eco-environmental protection and construction i n China. In the early 1980s, scientists brought forward that eco-agriculture is the direction of developing Sichuan agriculture. The main problems o f agricultural eco-environment in Sichuan are: the decreasing of virgin for es ts, the weakening of ecological function, the desertification and soil erosion due to unreasonable resources exploi tation and construction, the remaining of pesticides,fertilizers,plastic membran es, the pollution of municipal and industrial solid wastes,acid rain,manures of livestock, etc.. The countermeasures of improving Sichuan agricultural ecology i s to protect natural for ests, strengthen the protection of agricultural environment, construct agricultu ral ecology projects, startup agricultural cleaner production projects, pay more attention to eco-agriculture technical innovation. Through developing eco -technology industry, constructing ecological safety system, using industrial o peration model of company and farmer,integrating all kinds of information, the s ci-tech industry of eco-agriculture will develop rapidly.
