摘要:运用能值理论、方法，以植被NPP为基础，评价环境资 源系统对准格尔旗种植业系统的影响、贡献，揭示种植业系统的物质基础、运行效率和发展 方向。研究表明：(1) 环境资源，尤其可更新资源是准格尔旗种植业系统生产力的主要驱动 因素。优化能值投入结构，提高环境资源的利用率、转化率，是发展准格尔旗种植业系统生 产力的战略方向。(2) 准格尔旗种植业系统的可持续规模、产量主要取决于环境资源提供的 自然资本、生态服务。推广以木本水果、木本粮油为主体的农林复合系统，推进生态建设步 伐，进而增强环境资源提供自然资本、生态服务的能力，是维持准格尔旗种植业系统可持续 规模的最佳途径。(3) 实施“农牧互促”的农业发展战略，提高农牧业系统耦合度及其整体 生产力，尤其以种植业支撑畜牧业发展，提升农产品附加能值，是准格尔旗种植业系统的重 点发展方向。

AbstractThe theory and methods of emergy were adopted to evaluate the impact and contribution of nvironmental resources to farming system in Zhunger County based on NPP, so as to reveal the material basis, operating efficiency and development direction of farming system. The study showed: (1) Environmental resources, especially renewable resources were the main driving factors of farming system productivity in Zhunger County. Optimizing the emergy input structure and improving the utilization and transformation efficiency of environmental resources would be the strategic orientation to improve farming system productivity in Zhunger County. (2) The sustainable scale and yield of farming system in Zhunger County depended mainly on natural capital and ecosystem services that were provided by environmental resources. The best way to maintain the sustainable scale of farming system in Zhunger County would be promoting agro-forestry systems including woody fruits and woody grain and oil crops, accelerating the pace of ecological construction, and thus enhancing the capacity of natural capital and ecological services supplied by environmental resources. (3) The key development direction of farming system in Zhunger County could be implementing the strategy of farming and stockbreeding promoting mutually, improving the coupling degree and overall productivity of farming-stockbreeding system, particularly supporting the development of animal husbandry by farming, and enhancing the additional emergy value of agricultural products.
