“…Moreover, with the gradual enhancement of groundwater evaporation in the region, soil salinization in the Hetao Irrigation District (HID) has aggravated, seriously affecting the ecological, agricultural and socio-economic development of the region [4]. Therefore, the joint application of surface water and groundwater with the optimal scheduling strategy of well and channel combinations can be used to control the groundwater level of the area below the critical depth, and reduce soil salinity in the irrigation area; this can be a reference for controlling soil salinization in the area [5]. In the regional agricultural water and soil resource management system, there are complexities such as runoff, rainfall, planning period supply and demand, and fluctuations in economic parameters, in the measures to control the salinization of surface land, water and salt migration, and droughts or floods, which intensify the work uncertainty.…”

The average annual water diversion of the Hetao Irrigation District (HID) from the Yellow River is 4.5 billion cubic meters, mainly used for surface irrigation. Because the groundwater depth is shallow, strong evaporation conditions and unmatched irrigation conditions lead to serious soil salinization in the area; thus, the irrigation area’s ecological environment is fragile. Based on the current situation of the Yellow River irrigation project in the area, an interval two-stage robust stochastic optimization model is proposed to address the problem. In 2015, the Shuguang Experimental Station in the middle of the HID, Inner Mongolia, discussed the impact of different degrees of water–salt coordinated regulation on water consumption, yield and price of wheat, maize and sunflower under drip irrigation conditions. The obtained results provide the water shortage and water distribution targets of multiple water sources and multiple water levels in five irrigation areas of the HID. Those water distribution targets were used as the main input parameter and entered into the SALTMOD model based on the principle of water and salt balance. The output included data on groundwater mineralization and groundwater depth. It was observed that (1) integrated interval two-stage robust stochastic programming and the SALTMOD Model to couple optimization model under uncertainty can simulate a model together; (2) systemic risk issues were considered; and (3) the proposed method can be applied to the HID in northwest China to solve the soil salinization control problem. This approach is applicable to arid and semiarid regions that face similar problems.

“…Literature [10], in order to support agricultural water resource management, proposed a multiobjective interval stochastic planning method based on interval hierarchical projection and opportunity-constrained planning by improving the existing methods. Literature [11] analyses the dynamic and coordinated development level of the ecological-agricultural-urban space over ten years from the perspective of its ecological-agricultural-urban space, discusses the characteristics of spatial utilization, problems and development potential, and puts forward corresponding policy recommendations from the perspectives of ecological protection, economic transformation, and regional division of labor and co-operation.…”

This paper firstly constructs the matrix of eigenvalues of agricultural economy and ecological environment based on the original data, uses the entropy value method to judge the degree of dispersion of the indexes, determines the weights of the comprehensive evaluation index system of agricultural economy and ecological environment, and calculates the comprehensive scores of the agricultural economy and ecological environment system based on the weights of the indexes. Then, the synchronization development index model was used to express the coupled and coordinated development relationship between agroecology and agroeconomy. Finally, the regression analysis model was used to analyze the factors that affect the coupled and coordinated development of agroecology and agroeconomy. The level of agroecology in County A grew from 0.1 to 0.85, and the level of agroeconomy from 0.267 to 0.7. The value of agroeconomy and ecology coupling degree increased from 0.434 in 2010 to 0.683 in 2020, and it was gradually transformed from a dysfunction to a barely coupled one. This study deeply analyzes the influencing factors affecting the coupling and coordinated development of the agricultural economy and ecology, which is of great significance for promoting the high-quality development of the agricultural economy and maintaining ecological security.

“…Rivers, lakes, and wetlands are major components of natural water systems (Tan et al, 2018;Zhang et al, 2019;Liu et al, 2020;Meng et al, 2020). They are playing increasing roles in sustaining water not only for human beings but also for ecosystems.…”

With the intensification of climate change and human activities, the watershed ecosystem is seriously fragmented, which leads to the obstruction of hydrological connectivity, and further causes the degradation of the ecosystem. As the value of wetlands continues to be exploited, hydrological connectivity becomes increasingly significant. In this paper, the characteristics and development of hydrological connectivity research from 1998 to 2018 were analyzed through the scientometric analysis based on Web of Science database. CiteSpace, an analytical software for scientific measurement, is used to visualize the results of the retrieval. The analysis results of co-occurrence, co-operative and co-cited network indicate that the hydrological connectivity is a multidisciplinary field which involves the Environment Science and Ecology, Water Resources, Environmental Sciences, Geology and Geosciences. According to Keyword cooccurrence analysis, ecosystem, floodplain, dynamics, climate change and management are the main research hotspots in each period. In addition, the co-cited analysis of references shows that "amphibians" is the largest cluster of hydrological connectivity, and the "channel network" is the most important research topic. It is worth noting that the "GIWS" (Geographically Isolated Wetlands) is the latest research topic and may be a major research direction in the future.
