甘肃省临夏县张梁村遵循生态学原理、经过五年多的生态农业试点取得了显著的经济、环境及社会效益，农业生产走向良性循环的道路。同１９８６年相比，１９９０年资源（光能、土地等）利用率提高了６８．３％，森林覆盖率达２３．６％，在黄土高原已达较高水平。生态户农业总产值是试点前的３．９５倍，人均净收入提高了１２５２．２元，从根本上改变了贫穷面貌，转变了传统的农业生产结构和经营思想，按生态经济学原理创造了黄土高原上的“种—养—加”生态农业模式，同时也提高了土地及付产品的利用率，增加了资源使用价值亦改善了农村环境。
Zhang Liang Village, Linxia County, Gansu Province, follows the principles of ecology. After more than five years of pilot projects in ecological agriculture, remarkable economic, environmental and social benefits have been achieved and agricultural production has taken a virtuous circle. Compared with 1986, utilization of resources (light, land, etc.) increased by 68.3% in 1990 and forest coverage reached 23.6%, reaching a high level in the Loess Plateau. The total output value of ecological agriculture was 3.95 times of that before the pilot project, and the per capita net income increased by 1252.2 yuan, fundamentally changed the poverty outlook, transformed the traditional agricultural production structure and management ideas, and created the principles of ecological economics The “seed-raising-plus” eco-agriculture model on the Loess Plateau also improved the utilization rate of land and by-products, increased the value of resource use and improved the rural environment.
