Land-use patterns affected carbon emissions, which were influenced by urban land-use management in the long term. However, few studies linked emissions with composite directly, leading to difficulties reducing planning. Here, we proposed an integrated framework for accounting types and prediction through including adjustment of growth mode structure. And FLUS model linear programming scenario analysis predict emissions. Finally, a decoupling was used evaluate effects on decoupling. A case...
Currently, China will promote county towns' urbanization, and few studies have analyzed spatial effects of urban land-use intensity on CO2 emissions predicted at the level accurately. Here, taking data from 2010 to 2015 Zhejiang Province as an example, we effect three aspects input, density output by Durbin model (SDM). And then a machine learning method Back Propagation Neural Network (BPNN) was proposed predict for 2035 nonlinearly under different promotions intensity. The main result...
More than 100 countries have implemented pictorial health warnings on cigarette packages. However, few studies compared how consumers from different geographic and cultural contexts respond to warning content. The current study compares perceptions of among adult smokers youth in seven countries, examine the efficacy themes images.
The study of the land use optimization urban agglomerations is great significance to rational utilization resources and sustainable development agglomerations. Previous studies have simply regarded agglomeration as a whole area or each city an isolated individual, without considering regional coordinated in objectives. This proposed first attempt couple Zipf's law multiobjective model agglomeration. was applied quantify it one objectives optimization. genetic algorithm adopted establish...
To prevent the degradation and destruction of ecosystems, ecological restoration has become a worldwide issue. In recent years, China been comprehensively carrying out relevant work on national spatial planning, among which zoning can provide strong support for implementation strategies. We propose theoretical framework technical route from hydro-ecological perspective, suggest forming regional system based watershed as basic unit dynamic evolution process hydro-ecology core. conduct an...
Pesticide use in peri-urban areas affects the urban environment and public health, reducing may present food security issues for dwellers. In this study, we explore how a municipality-adopted goal of 20% reduction pesticide could be achieved, along with local environmental implications, Shanghai located densely populated East China. A regional Agricultural Sector Model incorporating district- technology-varying crop budgets, was developed to simulate effects policy. Here find that achieving...
The ‘Returning Farmland to Forest Program’ (RFFP) in China has become an essential factor land cover changes and forest transition, especially terms of the ecological processes between two adjacent ecosystems. However, accurately delineating ecotones is still a big challenge for vegetation landscape ecologists. Acquiring high spatial resolution imagery from small, unmanned aircraft system (UAS) provides new opportunities studying at small scale. This study aims extract forest-agriculture by...
High-quality development is a new-era requirement for modern urban construction. The implementation of construction land decrement has become an inevitable choice to solve the use dilemma and achieve high-quality social economic development. It game process stakeholders. Based on multi-agent model, this research analyzes relationship strategy selection between governments, government farmers, developers, developers farmers examines balance interests among multiple subjects. From perspective...
Using a structural equation model, this study explores the complex influence mechanism between place experience and satisfaction of historical cultural blocks in old city Beijing differences different types. Based on data obtained questionnaire survey, uses model method to propose theoretical relationship satisfaction, through path analysis, dimensions placeness, sense place, is estimated tested. Through mathematical verification basis establishing final hypothesis be proved further...
In this paper, we present what believe is the first demonstration of a new rectangular KD*P crystal as an electro-optic switch and calculations stress-induced birefringence depolarization loss in crystal. We simulated experimentally demonstrate thermal both cylindrical shape. The results show that by using crystal, effects thermally induced can be lessened.
We present a novel structure of planar waveguide for Yb:YAG laser amplifiers as symmetrical corner-pumped waveguide, allowing large absorption length. optimize the parameters using an amplification model. Performance including thermal effects 10-kW amplifier is simulated, demonstrating that pump efficiency and uniformity are much better than end-pumped ones. Moreover, good beam quality causing by less distortion can be expected. The power scaled from 200W to 7000W with 98.2%, leading...
As the utilization of renewable energy sources continues to expand, storage systems assume a crucial role in enabling effective integration and energy. This underscores their fundamental significance mitigating inherent intermittency variability associated with sources. study focuses on involvement photovoltaic (PV) plants medium long-term transactions. It also explores participation battery system (BESS) electricity trading frequency regulation ancillary services. The objective is establish...
The Central Axis of Beijing represents the epitome this typical feature ancient Chinese capitals. In 2020, government decided to extend it southward and northward, ushering in new opportunities for its protection development. Based on “Historical Urban Landscape” analysis framework, paper constructs an overall framework central axis, including historical evolution, relationship with Beijing’s macro landscape pattern changes, urban elements, property rights arrangement public opinion...
In this paper, on the basis of theory quasi phase matched, CO<sub>2</sub> laser spectrum corresponding to GaAs chip within scope matching length was calculated. Through numerical solution wave equation, relationship between power density pump and frequency doubling conversion efficiency given under different crystal conditions. By adjusting gas mixture components, we optimized pulse meet requirements in temporal distribution light. On other hand, optimize output beam mode light space...
