现阶段我国范围之内森林面积呈现出来一种逐渐减少的趋势,沙化面积呈现出来一种逐渐增加的态势,在此基础之上我国生态环境会遭受到较为严重的破坏,因此也就会让我国大部分省份当中出现一定程度的干旱问题,从而有也就会对我国粮食总产量造成一定程度的影响,只有在使得节约用水以及科学合理灌溉等目标得以实现的基础上,才可以让目前我国水资源利用分配需求得到满足,在水资源匮乏程度日益提升的基础上,环节水资源供需矛盾的过程中应当应用到的是节水灌溉技术措施,与此同时节水灌溉技术措施实际应用的过程中,也可以促使我国农业向着可持续发展的方向转变。
At this stage, the forest area within our country has shown a trend of decreasing gradually. The desertification area shows a gradually increasing trend. On the basis of this, the ecological environment of our country will suffer more serious damage and therefore will make our country A certain degree of drought will occur in most provinces, which in turn will affect the overall grain output in our country to a certain extent. Only by achieving the goals of water conservation and scientific and rational irrigation can the present water The demand of resource utilization and distribution is met. On the basis of increasing water scarcity, the contradiction between supply and demand of water resources should be applied to the technical measures of water saving irrigation. At the same time, the practical application of water saving irrigation technical measures , But also can promote China’s agriculture toward sustainable development.
