Rural cultivated land resources have become idle and ineffectively utilized. The cultivated land circulation status and its driving mechanisms were studied to vitalize the utilization of cultivated land resources. The study also aimed to provide theoretical support for targeted regional sustainable poverty alleviation and rural revitalization considering the organic connection between the two. Yanchi County, an area representative of targeted poverty alleviation and rural revitalization in the northwest arid region, was chosen for the study.The differentiation characteristics, controlling factors, and mechanisms of cultivated land circulation were investigated using ArcGIS and geographic detectors based on questionnaire survey data from 93 administrative villages. The results showed that there were significant regional differences in the circulation of cultivated land in Yanchi County with a moderate intensity in the central region and higher and lower intensities in the north and south, respectively. Per capita cultivated land area, irrigated land area, cooperative operation status,number of characteristic industries, and distance from the main road of the county level were the leading factors of cultivated land circulation, with determination values of 0.247, 0.264, 0.028, 0.065, and 0.091, respectively. Our results suggested that land use drives cultivated land circulation in Yanchi County. Cultivated land circulation and sustainable utilization can be achieved by constructing water conservancy projects and increasing irrigated land area and by strengthening agricultural cooperative management and characteristic industry development.

The aim of this work was mainly to study the distributions of selenium(Se)resource in soils to provide basic information for the exploitation of Se-enriched agricultural products in Ili District, Xinjiang Uygur Autonomous Region. Based on the analysis data of total Se content from 158 soil samples in six counties, the distribution characteristics of Se and the correlation with soil physicochemical properties were analyzed with the statistic method. The results indicated that the geometric mean value of Se content in the soils of Ili district was 0.33 mg·kg-1, ranged from 0.14 mg·kg-1 to 2.75 mg·kg-1. The soil in Zhaosu county had the highest average, and Gongliu county had the lowest. The statistics analysis showed that the percentage of low Se soil, full Se soil(0.17～0.45 mg·kg-1)and high selenium soil(0.45～3.00 mg·kg-1) was 2.38%, 78.57% and 19.05%, respectively. The content of total Se was significantly positive correlated with organic matter, available potassium and available nitrogen(P<0.01), while pH showed negative correlation with Se(P<0.01). High level of Se content in soils provided an opportunity to develop the Se-enriched agricultural products in Ili district. [ABSTRACT FROM AUTHOR]
