摘要
农业活动如化肥、农药、地膜的使用、高产品种的推广、节水灌溉技术的应用等,所导致的生境条件的变化和农田景观结构的不合理是影响农田生态系统物种多样性的重要原因。鉴于此,提出了保护农田生态系统物种多样性的几点建议:①建立可持续的生态农业;②进行合理的农田生态规划;③合理的混合种植不同作物,打破单一的种植结构。
The changes of ecological conditions owing to agricultural activities such as extensive usage of pesticides and fertilizers, extendibility of high yield breeds and application of water-saving in irrigation technology etc. and the irrationality of landscape structures of farmland have significantly impacts on the biodiversity of species of the agricultural ecosystems. So this paper makes some suggestions to protect the biodiversity of agricultural ecosystem: ①construct continuous ecological agriculture, ②make ecological planning of farmland rational, ③plant various crops rationally and break the single structure of planting.
