Fresh vegetable supply is highly dependent on long-distance cross-regional transportation with high costs and large losses, resulting in weak dietary support for remote scattered settlements and frontline management stations. Existing centralized vertical farms and large-scale photovoltaic greenhouses are difficult to deploy in widely dispersed scenarios due to high construction and operation costs and insufficient commercial returns. Meanwhile, China's photovoltaic manufacturing industry leads the world in production capacity, while the incremental margin of traditional application scenarios is narrowing, creating an urgent need for new sinking and scenario-based emerging markets. Border defense in western China is limited by geographical endowments, with long and costly fresh produce supply chains, leading to a natural asymmetry in garrison costs between the northern and southern sides of the border. Western mineral and coal development scenarios also present synergy potential between industrial tail gas carbon utilization and mine logistics support. 本文提出一套户用级光伏耦合闭环温室体系,将沙漠锁边治理的“三级嵌套自治、水盐闭环、阶梯滚动”范式下沉至人居尺度,构建以家庭与小型站点为单元的蔬菜自维持系统。技术层面,设计“防风围护层-立体栽培层-能源水盐核心层”三级嵌套微型单元,以小型离网光伏阵列驱动苦咸水净化、营养液闭环循环与环境调控,浓水集中纳入区域盐分处置体系,实现局地零盐碱排放;单元采用1–3层最优栽培构型,遵循“主粮外运储备、生鲜本地自供”的二元供给原则,优先利用自然光、辅以光伏补光,规避全人工光的高能耗陷阱;进一步耦合西部煤制油与煤化工尾气资源,构建工业碳源-农业固碳的原位碳闭环,破解高海拔CO₂分压不足的光合瓶颈。机制层面,提出与沙漠锁边治理、矿产资源开发协同的阶梯扩散路径,随生态治理与资源开发边界由内向外逐层推进,依次完成前沿站点配套、产业区普及、散居点覆盖,形成“公益配套先行、民间自主扩散”的落地节奏。 This paper proposes a household-scale photovoltaic coupled closed-loop greenhouse system, which extends the "three-level nested autonomy, water-salt closed loop, stepwise rolling" paradigm of desert fringe control to the human settlement scale, constructing vegetable self-sustaining units centered on households and small stations. Technically, a three-level nested micro-unit is designed, consisting of a windproof enclosure layer, a vertical cultivation layer, and a core energy-water-salt layer. Small off-grid photovoltaic arrays drive brackish water desalination, nutrient solution closed-loop circulation and environmental regulation. Concentrated brine is centrally incorporated into the regional salt disposal system to achieve zero local saline-alkali discharge. The unit adopts an optimal 1–3 layer cultivation configuration, follows the dual supply principle of "staple grains transported and stored from the rear, fresh produce supplied locally", prioritizes natural light supplemented by photovoltaic lighting, and avoids the high energy consumption trap of fully artificial light. It further couples with coal-to-liquids and coal chemical tail gas resources in western China to build an in-situ carbon cycle of industrial carbon sources and agricultural carbon sequestration, breaking the photosynthetic bottleneck of insufficient CO₂ partial pressure at high altitudes. Mechanistically, a stepwise diffusion path coordinated with desert fringe control and mineral resource development is proposed, advancing layer by layer from the inside out along with ecological governance and resource development boundaries, sequentially completing frontline station support, industrial zone popularization, and scattered settlement coverage, forming an implementation rhythm of "public welfare support first, folk independent diffusion later". 该体系不以商品化生产为目标,核心价值在于以极低的边际成本替代高价外购生鲜,提升干旱高海拔区人居舒适度与定居吸引力;同时可作为光伏产能的新型下沉消纳载体,带动配套装备产业增量发展;在国防与边疆治理维度,可精准削减补给链路中成本最高的生鲜环节,降低边防驻守总成本,收窄地理禀赋差异造成的驻守成本不对称;在资源开发维度,可与煤制油产业联动形成碳-菜原位循环,支撑西部矿产勘探与开采的长期后勤保障。本文从技术构型、闭环工艺、扩散机制与多维度效益框架完成体系设计,为干旱偏远区域民生供给、产业赋能与边疆治理提供兼具生态适配性与经济可持续性的新方案。 This system does not target commercial production. Its core value is to replace high-priced purchased fresh produce at extremely low marginal costs, improving living comfort and settlement attractiveness in arid high-altitude regions. It can also serve as a new sinking carrier for PV capacity absorption, driving incremental development of supporting equipment industries. In terms of national defense and border governance, it can precisely cut the most costly fresh produce segment in the supply chain, reduce the total cost of border garrison, and narrow the garrison cost asymmetry caused by geographical endowment differences. In terms of resource development, it can link with the coal-to-liquids industry to form an in-situ carbon-vegetable cycle, supporting long-term logistics support for mineral exploration and mining in western China. This paper completes the system design from technical configuration, closed-loop technology, diffusion mechanism and multi-dimensional benefit framework, providing a new scheme with ecological adaptability and economic sustainability for people's livelihood supply, industrial empowerment and border governance in arid and remote areas. 关键词:户用光伏温室;干旱高海拔区;蔬菜自维持;水盐闭环;阶梯扩散;光伏产能消纳;边防后勤成本;碳资源化;沙漠锁边配套 Keywords: Household PV Greenhouse; Arid High-Altitude Region; Vegetable Self-Sustainability; Water-Salt Closed Loop; Stepwise Diffusion; PV Capacity Absorption; Border Defense Logistics Cost; Carbon Resource Utilization; Desert Fringe-Control Support
