Currently, there is little research on this topic, and most of it neglects potential influence factors, leaving the corresponding supporting efficiency questionable. In this paper, we study the landing scheduling problem for carrier aircraft considering the effects of bolting and aerial refueling. Based on the analysis of recovery mode involving the above factors, two types of primary constraints (i.e., fuel constraint and wake interval constraint) are first described. Then, taking the landing sequencing as decision variables, a combinatorial optimization model with a compound objective function is formulated. Aiming at an efficient solution, an improved firefly algorithm is designed by integrating multiple evolutionary operators. In addition, a dynamic replanning mechanism is introduced to deal with special situations (i.e., the occurrence of bolting and fuel shortage), where the high efficiency of the designed algorithm facilitates the online scheduling adjustment within seconds. Finally, numerical simulations with sufficient and insufficient fuel cases are both carried out, highlighting the necessity to consider bolting and aerial refueling during the planning procedure. Simulation results reveal that a higher bolting probability, as well as extra aerial refueling operations caused by fuel shortage, will lead to longer recovery complete time. Meanwhile, due to the strong optimum-seeking capability and solution efficiency of the improved algorithm, adaptive scheduling can be generated within milliseconds to deal with special situations, significantly improving the safety and efficiency of the recovery process.

In alpine regions with limited direct human impact, long-term warming trends can enhance key proce-sses, such as algal growth and the mineralization of organic matter, thereby altering OC and IC accumulation and burial dynamics. We examined spatial patterns, synergistic relationships and controlling factors of carbon burial under regional warming across six alpine lakes in northwestern Yunnan (deep lakes: Dinggongniang Co, Gaigong Co Na, Wodi Co; shallow lakes: Dinggong Co, Bigu Tianchi, Shudu Lake), by employing multiple proxies including total nitrogen, chlorophyll, OC and IC contents, combined with climate reconstruction data. Results showed that 1.14 ℃ increase in temperature over the past 150 years had significantly reshaped carbon sequestration across lakes. The response magnitude of primary productivity to temperature increases in shallow lakes (Bigu Tianchi: 39%; Shudu Lake: 58%; Dinggong Co: 30%) was significantly greater than in deep lakes (Dinggongniang Co: 14%; Gaigong Co Na: 7%; Wodi Co: 20%). Distinct carbon cycling processes were observed between lake types. In deep lakes, algal contributions to OC were negligible while enhancing synchronous OC-IC deposition, indicating stratification simultaneously inhibited autochthonous carbon burial while promoting organic matter preservation. Conversely, there were strong chlorophyll-OC correlations with weakened OC-IC coupling in shallow lakes, revealing algal-dominated organic carbon production coupled with enhanced mineralization processes. Furthermore, atmospheric deposition altered inorganic carbon burial regimes through nitrogen enrichment in alkaline waters (Dinggongniang Co, Gaigong Co Na, Wodi Co, Shudu Lake, Bigu Tianchi). Elevated pH promoted carbonate precipitation and IC accumulation, while acidic inputs suppressed IC burial in acidic lake (Dinggong Co) and modified OC-IC burial relationship. Overall, the carbon burial processes in alpine lakes exhibited different responses to regional environmental changes, which were strongly related to lake depth, pH, and other limnological characteristics.</p>","PeriodicalId":35942,"journal":{"name":"应用生态学报","volume":"36 8","pages":"2475-2486"},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144972474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We synthesized multi-source data from field investigations, interview and literature to elucidate design principle of the zoned desertification control mode of desert-crossing highway grids, configuration characteristics of \"three belts\" (dune-fixing and forestation belt, enclosure conservation belt, and aerial seeding belt), vegetation and soil restoration processes, and influences on production and living. The results showed that the desert-crossing highway grids and the \"three belts\" protective system cut and separated large areas of active sand dunes, blocking sand source, controlling wind-sand hazards, promoting transportation, and facilitating people's livelihoods. After seven years of vegetation restoration, the number of plant species has increased to more than 16. The vegetation gradually changed from psammophytes to xerophytes. Both species diversity of vegetation and soil seed banks increased significantly. From the dune-fixing and forestation belt, enclosure conservation belt, and aerial seeding belt to uncontrolled active sand dunes in the center of a grid, soil water presented deficit, balance and surplus state, respectively, maintaining water balance in the grid as a whole. The mode in line with principles of aeolian sand dynamics and restoration ecology formed the pattern of \"highways cutting sand dunes, grids locking and fixing sand dunes, progressive restoration by the 'three belts', left blank to store water in the center\". This mode demonstrates the coordinated deve-lopment between controlling wind-sand hazards and restoring vegetation, constructing artificial vegetation and maintaining water balance, as well as coordinating ecology, production, and livelihoods. This mode embodies a top-level design philosophy guided by county-level planning units, multi-department collaboration, and integration of multiple technologies.
