In order to reveal dynamics changes in phosphorus release from the sediments of wetlands in a mid-temperature steppe without external phosphorus input, the relationship between phosphorus content in the overlying water, sediment, and interstitial water was studied using the variables control method. The results showed that, during the incubation period, the content of total phosphorus in the overlying water and the content of total phosphorus in interstitial water both presented in the order of August > September > July. Furthermore, the correlation relationships between phosphorus content in the overlying water, total phosphorus in the interstitial water, and the ratios of sediment Olsen-P to total phosphorus in the interstitial water, indicated that Olsen-P might be a kind of release form of phosphorus - from the sediment to the overlying water of the wetlands in Hulunbeier steppe, without external phosphorus input.

ecological quality is defined as the stability, adaptability and resilience of an ecosystem. Monitoring and assessing ecological quality are important bases for China’s ecological civilization construction. The national key research and development program "Technologies and guidelines for monitoring ecological quality of terrestrial ecosystems in China", launched in July 2017, includes plans to study the observation technologies and provide guidelines on the ecological in-situ observation, the regional biodiversity and ecosystem function monitoring and its applications, all of which contribute to national ecological quality assessment. A year after its implementation,some important progress has been achieved, such as building the indicator system for comprehensive monitoring of ecological quality and improvement of the methods, mass data transmission, infrared camera-based monitoring of biodiversity, multi-angle automatic spectral observation systems, and unmanned aerial vehicle(UAV) based desert monitoring. We have organized this special issue and attempted to introduce the monitoring techniques and assessment methods on ecological quality from different perspectives in order to further promote the development of ecology and its observation methods.

The drive towards clean energy sources has prompted the worldwide construction of emerging photovoltaic solar parks. The intense Despite the advantages of lower pollutant and greenhouse gas emissions, the construction of solar parks (SP) is not without environmental and ecological consequences due to changes in land use and impacts on regional climate. Previous studies have reported that SP construction impacts microclimate, plant biomass, biodiversity, soil physicochemical properties, and soil microbial community structure. However, our understanding of how SP influences a wide range of ecosystem functions simultaneously remains incomplete. To address this gap, we assessed the changes in ecosystem multifunctionality (EMF) in SP habitats in arid ecosystem, by measuring twenty-three indicators related to ecosystem functions comprising primary production, soil nutrient pool, carbon cycling, nitrogen cycling, phosphorus cycling and oxidation-reduction. Furthermore, we identified the primary driving factors and regulatory mechanism of EMF in different periods since SP installation. The results showed that SP had positive effects on EMF indices, the positive effect size was higher in initial installation period (5.4%-149.0%) than in constant running period (0.4%-15.3%). The enhancement in EMF were mainly due to the enhanced nutrient cycling induced by increased abundance of fungal indicator taxa (Indicator) as well as microbial biomass and metabolic efficiency (MBM) according to the results of variance decomposition analysis and multiple linear regression. Moreover, the structural equation model revealed distinct regulatory mechanism between the two period, and a transition in the primary driving factors of EMF from Indicator to MBM. Together, our study reveals the different effect size of SP on EMF and changes in driving factor and regulatory mechanism of EMF during the different periods following SP installation. These findings complement the environmental impact analy
