Abstract
Optimization of open space plays a significant role in achieving sustainable development of ecological cities.Green open space system in Luoyang consists of 6 categories: product area,farmland and forest,riparian area,garden,road landscape area and auxiliary area.By using landscape pattern analysis,Structure Evenness Radio Index,Ecological Intensity Index,and Huff model,the paper examines the dynamic changes in area,shape and distribution of the open space from 1988 to 2008.It evaluates service capacity of the open space system before spatial distribution and demand-supply condition is optimized.Results are shown as follows.1) For the 20 years there is an increase in riparian areas,gardens,road landscape areas and auxiliary areas,while a decrease in product area,farmland and forest.Green space is abundant in Quadrants 2-5 and Rings 4-8,and less in Quadrants 7 and 8 and Rings 1,2,and 10.2) There are significant differences in Evenness Radio of all quadrants and rings.However,Quadrant 6 and Ring 5 show stable Evenness Radio,indicating gradual improvement of space distribution in riparian areas,gardens,road landscape areas and auxiliary areas.3) There is a notable increase in density of patches,with areas along the Luohe River and west fringe of the city having the highest value.Many patches have low Shape Index,though some regions see an increase.The patches generally display regular geometry shapes,which are obvious products of urban planning.4) Ecological Serving Intensity Index of 2008 is 0.288,and falls into Class III,being an ordinary level.Time costs for local residents visiting open space are high.Demand and supply of space service are out of balance for both the northern and southern parts of the city.5) The frame of overall design for open space system optimization is 1 center with 3 rings,4 belts with 3 axes,and 3 mountains with 4 wedges.The four levels of optimizing distribution pattern are green rings revolving,green corridors interweaving,green dots interspersing and background extending.Residence location and space distribution need to be modified to find the balance in demand and supply of space.Concrete measures should be taken to optimize the distribution and functionality of public open system.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
