“…By tailoring the localized average natural grain yield, the equivalent weight factor, as shown in Table 2, can be applied to different regions of China. As a benchmark, the economic value of average natural grain production of farmland per year was set at 1.0 [10,25,31,39,41,46]. Based on this factor, all other coefficients were adjusted accordingly.…”

“…Several studies have been performed to monitor the impact of LULC changes on the structure and functions of ESV in numerous regions of China [4,10,18,[23][24][25][26][27][28][29][30][31][32][33] and around the world [15,25,28,29,[34][35][36][37][38][39][40][41][42][43][44][45]. Due to LULC changes and urbanization, most of these studies showed moderate to significant decrease in ESV [15,16,28,29,41,43] while others found almost no change [46]. Some studies have also revealed an increase in ESV [47][48][49][50].…”

The rapid increase in anthropogenic activities, socioeconomic development, and land use land cover (LULC) changes since the opening of economic reforms (1978), have changed the ecosystem service value (ESV) in Guangdong, Hong Kong, and Macao (GKHM) region located in South China. This leads to the requirement of a significant tailored analysis of ecosystem services regarding incisive and relevant planning to ensure sustainability at regional level. This study focuses on the use of Landsat satellite imagery to quantify the precise impact of LULC changes on the ecosystem services in GHKM over the past three decades . The most renowned established unit value transfer method has been employed to calculate the ESV. The results show that the total ecosystem service value in GHKM has decreased from 680.23 billion CNY in 1986 to 668.45 billion CNY in 2017, mainly due to the decrease in farmland and fishponds. This overall decrease concealed the more dynamic and complex nature of the individual ESV. The most significant decrease took place in the values of water supply (-22.20 billion CNY, -14.72%), waste treatment (-20.77 billion CNY, −14.63%), and food production (-7.96 billion CNY, −33.18%). On the other hand, the value of fertile soil formation and retention (6.28 billion CNY, +7.26%) and recreation and culture (5.09 billion CNY, +12.91%) increased. Furthermore, total ESV and ESV per capita decreased significantly with the continuous increase in total gross domestic product (GDP) and GDP per capita. A substantial negative correlation exists between farmland ESV and GDP indicating human encroachment into a natural and semi natural ecosystems. The results suggest that in the rapidly urbanizing region, the protection of farmland and to control the intrusion of urban areas has marked an important societal demand and a challenge to the local government. This required a pressing need for smart LULC planning and to improve policies and regulation to guarantee ecosystem service sustainability for acceptable life quality in the study area and other fast expanding urban areas in China.

“…To assess the potential impact of land resource changes on agricultural irrigation water use, a sensitivity index was introduced to analyze the sensitivity of agricultural irrigation water use to land change. As a quantitative analysis method, sensitivity analysis is used to study the effect of one variable on another or a set of key indicators [38]. In this study, the subject of sensitive analysis is AIW, and the sensitive factors are FA and EIA.…”

Agricultural water and land resources are key elements of human production and their unbalanced distribution has threatened the sustainable development of agriculture and regional food security. This study is aiming to investigate the spatial-temporal changes of matching characteristics between agricultural water and land resources in Ningxia during 2007 to 2017. The agricultural irrigation water (AIW), farmland area (FA) and effective irrigated area (EIA) were selected as quantity parameters for agricultural water and land resource. Results show that the gravity centers of AIW and EIA both moved in the southeast direction, while the gravity center of FA moved northwestward, which indicated a better spatial matching degree between AIW and EIA. According to the Gini coefficient and total spatial mismatch index, the spatial mismatch between AIW and FA of Ningxia was remedied and that of AIW and EIA was worse. Counties with sufficient and insufficient AIW were distributed in the north and the south of Ningxia, respectively. The sensitivity of agricultural irrigation water to land resources remarkably increased in the study period, particularly for the counties in northern area of Ningxia. The findings may provide implications for effective management of regional agricultural water and land resources.

The Qinghai-Tibet Plateau is a more sensitive area of climate change and fragile zone of ecological environment. Qinghai Province is an important component of the Qinghai-Tibet Plateau, and the study of streamflow in the province is of great significance for understanding the situation of water resources. Based on hydrological data of hydrological stations in Qinghai, the spatiotemporal variations of streamflow from 1956 to 2013 were analyzed by Mann-Kendall analysis and Morlet wavelet analysis. The results indicated that the annual streamflow of the Yangtze River basin, Qaidam basin, Qinghai Lake basin, and Lantsang River basin showed significantly increasing trends during 1956-2013, while the Yellow River basin showed no significant trends or downward trends. Changes in precipitation, glacier melt, and snowmelt caused by climate warming might be a major driver of changes of streamflow in the source regions of the Yangtze River and Lantsang River basins. The trend variations of flow in the Yellow River basin may be affected by precipitation, evaporation caused by increased temperature, and anthropogenic impacts. The abrupt changes of streamflow at Tuotuohe, Delingha, and Nachitai stations were mainly in the early 2000s, while the abrupt changes of streamflow in Zhimenda station, stations in the Yellow River basin, Qinghai Lake basin, and Lantsang River basin appeared primarily in the early 1960s and the early 2000s. Most of the streamflow in Qinghai Province was abundant after about 2007, and the dominant periods with low frequency fluctuation (about 12 years) and inter-decadal (about 44 years) oscillations in Zhimenda and Tangnaihai stations and low frequency fluctuation (about five years) in other stations.
