“…This suggested that TDS might not be suitable for analyzing changes in soil quality of paddy fields in cold regions. In contrast, the MDS can accurately reflect soil quality, reduces data redundancy, and is highly adaptable [37,72]. The reliability of MDS was verified through correlation, E f and E R , indicating that MDS outperformed TDS in effectively and accurately evaluating soil quality, and provided valuable information for farmland management.…”

Soil quality is an indicator of the ability to ensure ecological security and sustainable soil usage. The effects of long-term straw incorporation and different irrigation regimes on the yield and soil quality of paddy fields in cold regions remain unclear. This study established four treatments: controlled irrigation + continuous straw incorporation for 3 years (C3), controlled irrigation + continuous straw incorporation for 7 years (C7), flooded irrigation + continuous straw incorporation for 3 years (F3), and flooded irrigation + continuous straw incorporation for 7 years (F7). Analysis was conducted on the impact of various irrigation regimes and straw incorporation years on the physicochemical characteristics and quality of the soil. The soil quality index (SQI) for rice fields was computed using separate datasets for each treatment. The soil nitrate nitrogen, available phosphorus, soil organic carbon, and soil organic matter contents of the C7 were 93.51%, 5.80%, 8.90%, and 8.26% higher compared to C3, respectively. In addition, the yield of the C7 treatment was 5.18%, 4.89%, and 10.32% higher than those of F3, C3, and F7, respectively. The validity of the minimum data set (MDS) was verified by correlation, Ef and ER, which indicated that the MDS of all treatments were able to provide a valid evaluation of soil quality. The MDS based SQI of C7 was 11.05%, 11.97%, and 27.71% higher than that of F3, C3, and F7, respectively. Overall, long-term straw incorporation combined with controlled irrigation increases yield and soil quality in paddy fields in cold regions. This study provides a thorough assessment of soil quality concerning irrigation regimes and straw incorporation years to preserve food security and the sustainability of agricultural output. Additionally, it offers a basis for soil quality diagnosis of paddy fields in the Northeast China.

“…Therefore, it is of great practical significance to carry out research on the change of cultivated land spatial distribution characteristics. In recent years, the cultivated land resources spatial-temporal change and driving mechanism have become a hot issue studied by many scholars at domestic and abroad, which mainly focuses on the cultivated land spatial distribution [3] , spatial-temporal change and driving mechanism [4][5][6][7] , and cultivated land quality [8][9] . Yangzonghai lake is one of the nine plateau lakes in Yunnan province.…”

【Objective】In order to grasp the quantity of cultivated land in Yangzonghai basin, the temporal and spatial variation characteristics of cultivated land were analyzed, which could provide a reference basis for the sustainable utilization of cultivated land resources and land spatial planning in Yangzonghai basin. 【Method】Based on ArcGIS, Fragstats 4.2 and other software, the RS data from 2005, 2010, 2015 and 2020 were selected to analyze the dynamic variation and spatial distribution pattern of cultivated land in the study area using different methods such as dynamic variation degree, different terrain conditions, transition matrix, geo-informatic atlas, and landscape pattern index. 【Result】From 2005 to 2020, the number of cultivated lands in the study area showed a decreasing trend with a reduced area of 816.45hm2 and a dynamic variation degree of -0.66%. From the county (district) scale, Yiliang County showed a continuous decline trend in the past 15 years, while the other three counties (districts) increased and decreased in each period; The topographic conditions had a certain impact on the cultivated land spatial distribution. The cultivated land in the study area occupies a large proportion in the cloudy aspect and semi-cloudy aspect with the altitude < 2300m and slope < 25°; From the perspective of geo-informatic atlas and landscape pattern index, cultivated land increased and decreased in each period from 2005 to 2020. The main types of land increasing are forest land, unused land and construction land, among which forest land accounted for a large proportion, indicating that the local ecological protection measures such as "returning farmland to forest" had achieved certain results. The landscape pattern index changed in each period from 2005 to 2020. Throughout the 15 years, the number of cultivated land patches had increased, and the average patch area and aggregation degree had decreased, indicating that the overall spatial aggregation of landscape pattern had weakened, the trend of landscape fragmentation had been presented. 【Conclusion】Based on the RS data of 2005, 2010, 2015 and 2020, the spatial distribution pattern changes of cultivated land in Yangzonghai basin in recent 15 years were analyzed from different angles by using the methods of dynamic variation degree, different topographic conditions, transfer matrix, geo-informatic atlas and landscape pattern index, so as to provide an important basis for rural revitalization and village planning in the future.

“…Soil quality can be quantitatively assessed based on a set of soil properties that affect soil functions, such as physical, chemical, and biological properties (Davari et al, 2020; Gil‐Sotres et al, 2005; Griffiths et al, 2010; Nosrati et al, 2011; Yakovchenko et al, 1996). At the moment, comprehensive soil quality evaluation methods primarily include soil quality cards and test kits (Ditzler & Tugel, 2002), the gray correlation method (Yang, Yang, et al, 2010), fuzzy methods (Torbert et al, 2008; Xue et al, 2010), and soil quality indices (Andrews et al, 2004; Jahany & Rezapour, 2020; Jin et al, 2021; Masto et al, 2008; Nabiollahi et al, 2017; Nakajima et al, 2015; Shao et al, 2020; Zhang, Xu, et al, 2019). Out of all the methods, the soil quality index (SQI) approach has been applied more frequently because of its flexibility and simplicity (Derakhshan‐Babaei et al, 2021; Zhang et al, 2021).…”

Soil quality is a critically important component of soil within ecosystems, and our understanding of soil quality variation and its driving factors in tropical forests is limited. This study collected soil samples at 0-20 cm depths from two typical tropical forests (tropical rainforest and rubber plantation) on Hainan Island, China's largest tropical island, during dry and rainy seasons. A soil quality index (SQI) using principal component analysis was applied to measure soil quality based on 21 soil properties.The soil properties' spatial and seasonal changes and their driving factors were simultaneously collected for a holistic analysis of the ecosystems. The results were summarized as follows: (i) The SQI of the rubber plantation decreased by 26.48% compared to the tropical rainforest on the island, while four soil properties investigated (soil pH, total phosphorus, cellulose decomposition, and actinomycetes) increased. (ii) The SQI of different soil types in the two tropical forests displayed an apparent discrepancy. Within the same soil type, the SQI of tropical rainforests showed no obvious differences, while there was a notable spatial discrepancy among rubber plantations in dispersed geographical positions belonging to varied climatic zones. (iii) The SQI of the tropical rainforest was significantly higher in the wet season than in the dry season. In contrast, there were no significant differences between the two seasons for rubber plantations, indicating that soil quality in the tropical rainforest was more sensitive to seasonal changes than soil quality in rubber plantations.Overall, we concluded that except for land use and soil type, spatial variability and seasonal pattern also played essential roles in soil quality on the tropical island. The results from the SQI are expected to provide novel information regarding the sustainable use of tropical forests on Hainan Island.
