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。
運用能值理論、方法，以植被NPP為基礎，評價環境資源繫統對準格爾旂種植業繫統的影響、貢獻，揭示種植業繫統的物質基礎、運行效率和髮展方嚮。研究錶明：（1）環境資源，尤其可更新資源是準格爾旂種植業繫統生產力的主要驅動因素。優化能值投入結構，提高環境資源的利用率、轉化率，是髮展準格爾旂種植業繫統生產力的戰略方嚮。（2）準格爾旂種植業繫統的可持續規模、產量主要取決于環境資源提供的自然資本、生態服務。推廣以木本水果、木本糧油為主體的農林複閤繫統，推進生態建設步伐，進而增彊環境資源提供自然資本、生態服務的能力，是維持準格爾旂種植業繫統可持續規模的最佳途徑。（3）實施“農牧互促”的農業髮展戰略，提高農牧業繫統耦閤度及其整體生產力，尤其以種植業支撐畜牧業髮展，提升農產品附加能值，是準格爾旂種植業繫統的重點髮展方嚮。

The theory and methods of emergy were adopted to evaluate the impact and contribution of environmental 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 re-sources 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 ori-entation 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 re-sources .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 stock-breeding 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 a-gricultural products .
