The identification of the multifunctional combination production–living–ecological spaces (PLES) in urban agglomerations, particularly cores and peri–urban areas, is a critical issue urbanization process. This study, using Hohhot–Baotou–Ordos–Yulin (HBOY) agglomeration, key node China’s “Two Horizontals Three Verticals” strategy, proposes hexagonal grid–based PLES quantification framework POI data. A three–level classification system was developed, with functional element weights determined via Analytic Hierarchy Process public perception surveys. quantifies within grids analyzes its patterns coupling mechanisms spatial overlay, Average Nearest Neighbor Index (ANNI), kernel density analysis, autocorrelation analysis. following results were obtained. (1) accuracy reached 90.83%, confirming reliability method. (2) HBOY agglomeration exhibits dominant production space (40.84%), balanced living ecological (29.37% 29.36%, respectively), severe shortage mixed (0.43%). (3) Production show significant clustering (ANNI ≤ 0.581), follow = 0.660), are relatively evenly distributed 0.870). (4) distribution that exhibit “core concentration peripheral dispersion”, “block point–like distribution”, “point–like dispersion”. (5) strong (Moran’s I > 0.7) highest correlation (Bivariate Moran’s 0.692), while weakest 0.150). proposed framework, efficiency dynamic updating potential, provides an innovative approach to governance under global Sustainable Development Goals. findings offer integrated decision–making support for diagnosis regulation ecologically vulnerable areas northwest new urbanization.

This paper deals with the issue of air cooling in outdoor areas human habitation. An analysis parameters during summer season was carried out to determine thermal comfort zone for a part northern platform local station Rzeszow (Poland). The capacity required calculated using and heat gains vicinity research object. Ten potential air-cooling systems were proposed zones. differed terms equipment, primary energy source, medium, recipients. They divided into three categories: compressor, adsorption, evaporative cooling. electricity yield existing photovoltaic installation at facility evaluated identify synergies between demand solar energy. assessed energy, economic, environmental impact each option. best option found be an system PV system. Solar radiation can effectively used zones Poland summer. optimal solution is based on direct evaporation combined subject matter covered as effective tool selection ensure occupants.
