鄂尔多斯高原农业开发和生态变迁的回顾与反思

Review and Rethink on the Agricultural Exploitation and Ecosystem Change in Ordos Plateau

历史时期,鄂尔多斯高原的农业开发,以汉、唐、清三代最为恢宏。从唐代开始,该区的生态环境明显恶化,渐向沙漠生态转变。不合理的农业开发通过直接与间接的作用,诱发、促进了沙化的发生发展。鄂尔多斯高原的现代农业开发,应以史为鉴,走治理与开发相结合的道路,重新分配人口,安排生产。同时,要充分发挥、协调各种科学技术的生态、经济作用。在缺乏灌溉条件的地区,可发展径流农业。

From Tang dynasty, the ecosystem in Ordos plateau began to worsen distinctly and then turned into desert-ecosystem. Unreasonable reclamation had directly, or indirectly brought out and accelerated desertification. The best way for the modern agri-cultural construction in Ordos plateau is to combine harnessing with exploitation. It is also possible and necessary to adjust man-land ratio and agricultural distribution, and bring all kinds of techniques into full play. Runoff agriculture can be set up in the areas where the irrigation conditions are poor.
