Effective pretreatment of spectral reflectance is vital to model accuracy in soil parameter estimation. However, the classic integer derivative has some disadvantages, including information loss and introduction high-frequency noise. In this paper, fractional order algorithm was applied partial least squares regression (PLSR) used assess clay content desert soils. Overall, 103 samples were collected from Ebinur Lake basin Xinjiang Uighur Autonomous Region China, as data sets for calibration...

The sequestration of carbon in forests plays a crucial role mitigating global climate change and achieving neutrality goals. Carbon use efficiency (CUE) is an essential metric used to evaluate the capacity Vegetation. Previous studies have emphasized importance assessing CUE at specific regions times better understand its spatiotemporal variations. southeastern region Tibet Qinghai-Tibet Plateau recognized as one most biodiverse areas China globally, characterized by diverse vegetation types...

The transformation of the landscape structure in mining cities is influenced by a combination various factors, resulting decline ecological quality and an increased vulnerability environment. ecology directly impacts flow transmission ecosystem functions, underscoring need for careful consideration establishment networks. In this study, analysis was conducted using land-use data from 2005 to 2020 Linfen City, Shanxi Province, China. A network optimization strategy established, focusing on...

There exists serious heavy metal contamination of agricultural soils in China. It is not only time- and labor-intensive to monitor soil contamination, but it also has limited scope when using conventional chemical methods. However, the method monitoring based on vegetation hyperspectral technology can break through barrier obtain content quickly over large areas. This paper discusses a highly accurate for predicting techniques. We collected leaf data outdoors, samples analysis. The...

In recent years, the accelerated pace of urbanization has increased patch fragmentation, which had a certain impact on structure and ecological environment forest–grass networks, protection measures have been taken in various regions. Therefore, studying spatiotemporal changes correlations service functions networks can help to better grasp landscape function. This paper takes Wuding River Basin as research area uses windbreak sand fixation capacity index, soil conservation capacity, net...

In the context of strengthening construction ecological civilization and accelerating “carbon peak” in China, regional pattern its connection with carbon sink capacity have become an urgent topic. Given that Inner Mongolia is a large emission province conflict between economic development protection particularly prominent, we took as example to extract ecospatial network, then calculated integrity index, topological indices, recovery robustness network evaluated other properties structure by...

The Biome-BGC model is a classic forest ecosystem carbon cycle driven by remote sensing and plant trait data, it has been widely applied in various regions of China over the years. However, does have good applicability all China? This question implies that rationality some applications might be questionable. To quantitatively assess overall spatial China’s vegetation ecosystems, this study selected ten representative grassland sites, which publicly available flux data. In study, we first...

The sand-stabilising, xeric shrub Artemisia ordosica Krasch. has experienced widespread decline decades after being widely distributed through seeding in the Mu Us Sandy Land China. role of biocrusts A. populations received attention but not been directly confirmed. To clarify effects on decline, a field study was conducted with different biocrust treatments (bare sand, lichen biocrust, moss removed) August 2019 North In each treatment, age structure, dynamic indices, and reproductive...

This paper tries to introduce extenics theory into the evaluation of urban community home-care service for elderly. The analyzes feasibility using evaluate service, uses analytic hierarchy process decide weight index and constructs a comprehensive model on basis extenics. Based case study communities in Ningbo, has completed operation put forward countermeasures existing problems.

Mapping the spatial distribution of artificial grassland for ecological restoration is great significance evaluating its secondary degradation and negative consequences, such as nonpoint source pollution water bodies in Three-River Headwaters (TRH) region. Because numerous challenges faced obtaining ground training samples caused by adverse natural conditions, inclement cloudy weather spectral similarity between grassland, commonly used classification or temporal-profile extraction methods...

Accurate monitoring and estimation of heavy metal concentrations is an important process in the prevention treatment soil pollution. However, weak correlation between spectra metals makes it difficult to use spectroscopy predicting areas with a risk In this paper, method for detection Ni eastern China using fractional-order derivative (FOD) spectral indices was proposed. The visible-near-infrared (Vis-NIR) were preprocessed FOD (range: 0 2, interval: 0.1) solve problems baseline drift...

Asiatic black bears (Ursus thibetanus laniger) are natural inhabitants of deciduous forests.They live solitary in their habitat.Their captive behaviour was studied by taking two bear pairs as study subjects Lahore Zoo, Pakistan.The based on the provision environmental enrichments to pairs.Each pair's pre-enrichment activity budget data collected scan sampling method 70 h, documenting cage area and behavioural ethogram.The observed behaviours were resting, eating, drinking, locomotion,...

In order to assess the health risks of heavy metals in surface water Qingjiang River, samples were taken at designed cross-sections river and analyzed for Cr, Cu, Zn, Pb, Cd, As, Mn. Health from these adults children wet dry seasons compared by environmental risk assessment model USEPA.
