“…In addition to affecting the rejuvenation rate of Phragmites australis, the stand dieback can also lead to population degradation, causing the Phragmites australis plants to become short and "hairy". For example, the density, height, diameter, and aboveground biomass of the Phragmites australis plants in Baiyangdian increased significantly after harvesting and management compared to the untreated community [7], as shown in Figure 1. Balanced harvesting management patterns also had significant effects on the growth and development of submerged plants.…”

“…The chemosensory effect of Phragmites australis was stronger and the species monoculture was higher once. Balanced harvesting promotes the good growth of Phragmites australis, increases the net photosynthetic rate of leaves, and facilitates the uptake of N and P from the surrounding environment by Phragmites australis [7]. Phragmites australis have high fiber content and tough stalks, and after the end of their life cycle, if not harvested, the dieback can still maintain a special standing form.…”

Macrophytes are the main primary producers in lake ecosystems and are the main transmitters of material and energy flows in lake ecosystems, directly influencing the structure and function of lake ecosystems. The balanced harvesting of aquatic plants is a cost-effective scientific management approach to maintain ecosystem health. The article defines “balanced harvesting” as an aquatic plant harvesting technique to optimize the structure of aquatic plant communities, maintain the normal function of the ecosystem material cycle and energy flow, and enhance the stability and resilience of the system. The ecological significance of balanced harvesting in regulating the evaporation coefficient of the subsurface, reducing the accumulation and release of endogenous nutrient loads in lakes, delaying the evolutionary process of marshification, inhibiting biological filling, increasing biodiversity and system stability, and improving the environment of water bodies under the natural laws of adapted aquatic plants is reviewed. The way, time, and method of the balanced harvesting of aquatic plants in Baiyangdian, a grass-type lake in the north, were analyzed in order to provide an important reference for wetland ecological restoration and protection, maintaining the health of the aquatic ecosystem, and making the lake environment sustainable.

“…In wetland restoration projects, the ecological recovery of reeds is often used as an important indicator [10]. Therefore, a comprehensive investigation of the area and spatial distribution of wetland reeds is of great significance for wetland protection and restoration [11]. Remote sensing technology is low-cost, fast, and spatially and temporally continuous, and has been widely applied to the classification, spatial and temporal distribution characteristics and biomass assessment of wetland vegetation [12][13].…”

This study investigated the spatial changes in reed distribution in Baiyangdian, using high-resolution remote sensing imagery. It revealed a substantial alteration in the distribution of reeds within Baiyangdian from 2016 to 2022. The reeds have converted with five types of land cover, including water, cropland, orchards, woodlands and building land. The reed area increased by 14.3% to 103.7 km2 in 2022 compared to 2016. The expansion primarily occurred in the shallow waters of Zaozhadian in the western part of Baiyangdian. The expansion of reed area is attributed to the continuous water replenishment in order to preserve the ecology and the restoration of cultivated land to wetland ecosystem. After the removal of the dyke, the 26.55 km2 of reed swamp on the dyke became open water. It increases the hydraulic connectivity of Baiyangdian lake and accelerates the restoration of ecological function of Baiyangdian Lake.
