The ecological quality of a region is significantly influenced by its geographical conditions, which can yield different effects on ecosystems. Nevertheless, the lack adequate technology has impeded quantitative investigations into these differences. Consequently, there an increasing demand for effective techniques to quantitatively measure differences in resulting from variations conditions. This study applied novel Remote Sensing-based Ecological Index (RSEI) concurrently two distinct provincial-level regions China, Fujian and Ningxia, detect their These possess contrasting with having high forest coverage abundant rainfall, while Ningxia features low extensive loess plateau desert terrain. By linking factors corresponding responses, we conducted comprehensive analysis determine whether conditions between had caused significant disparities status. results indicate that have indeed led marked differences, exhibiting excellent status, lags behind due unfavorable In terms RSEI scores, consistently achieved higher values (>0.8) years, reaching level, whereas recorded scores lower than 0.45 during comparable poor moderate level. Regarding impact positive contributions greenness wetness indicators ecology were greater those (58% vs. 39%), negative indicators, dryness hotness, notably compared (|–61|% |–42|%). successful concurrent application geographically distant also demonstrates robustness technique.

The evaluation of regional ecological status has far-reaching significance for understanding conditions and promoting sustainable development. Herein, a geospatial index (GEI) was developed on the basis Landsat data principles soil lines spatial geometry. Specifically, GEI integrates four remote sensing indicators: Perpendicular Vegetation Index (PVI) representing greenness, Modified Drought (MPDI) drought, Normalized Difference Built-up Soil (NDSI) dryness land surface, Land Surface Temperature (LST) hotness surface. Two typical regions, Fuzhou City Zijin mining area, in Fujian Province, China, were selected to evaluate quality via proposed GEI. results show an improvement overall City, with increase average value from 0.49 2001 0.53 2020. In case regions poor are concentrated main areas. However, rose 0.51 1992 0.57 2020, illustrating its conditions. study demonstrates robustness effectiveness GEI, objectively revealing distribution status.

Abstract The main acceleration of climatic changes is considered to be the consequences existing anthropogenic influences and transformations in wood ecosystems Steppe Dnipro industrial areas. Now, preparation science-based programs for restoration development artificial tree plantations, which can increase stability diversity forest steppe zone under these conditions, very important. However, shrub plantations are formed according certain natural laws. It necessary urgent study current state phytodiversity ensure effective protection biodiversity, implement nature conservation management on this basis, including expansion areas reserves. purpose research work was assess structure woody using example dust-protection water-protection sanitary plantations. Modern ecotopes region Ukraine, quite specific, primarily due combination landscapes territories. Depending ecological location territory taking into account vitality indicators further vectors progress or regression possible. Hence, there an need biometric Kryvyi Rih district’s different growth conditions. carried out will become basis directions preservation reproduction territory, make it possible plan biological trees districts. identifying features local guarantee rare species from various lists. also contribute provision ecosystem services by natural, spontaneous Middle region. received recommendations form complex measures preserve restore stable district, located steep slopes mine dumps rafter-beam systems near rivers water reservoirs Steppe.
