    Influence path and control measurement of COVID-19 on agricultural land use
    ZENG Guang, FU Han-yang, LI Chun-hua
    HUBEI AGRICULTURAL SCIENCES    2022, 61 (17): 88-92.   DOI: 10.14088/j.cnki.issn0439-8114.2022.17.012

    The COVID-19 pandemic has had an unprecedented impact on agricultural and forestry land use. So, it is of great significance to discuss the impact path and management approach of COVID-19 on agricultural and forestry land use. Firstly, a basic analysis framework of the impact of COVID-19 on agricultural land was constructed based on the relevant theories of the impact of COVID-19 on land. Secondly, case analysis, content analysis and comparative analysis were used to explore the impact of the epidemic on agricultural land use from two aspects: the impact path of the epidemic and the behavior response of land use subjects. Then, targeted solutions were proposed for the impact of the epidemic on them. Studies have found that the COVID-19 pandemic was affecting agricultural and forestry land use in many different ways to varying degrees, in terms of productivity, means of production, transport conditions, production technologies, food security and the natural and social environment. However, in the process of research, it was also found that although the epidemic had a great impact on agricultural land use, if the national government, relevant departments and people effectively cooperate, there were still relevant solutions and plans with practical value, such as rational land use decisions, adjustment of sown area, sustainable land use measures, transformation of planting patterns, and implementation of digital enabling agricultural technologies.

    Evaluation of land ecological security in Xinjiang based on DPSIR-TOPSIS method
    ZHANG Xiao-juan, GAO Min-hua
    HUBEI AGRICULTURAL SCIENCES    2022, 61 (17): 104-109.   DOI: 10.14088/j.cnki.issn0439-8114.2022.17.015

    Based on DPSIR model, the driving force - pressure - state - impact - response evaluation index system was established, and TOPSIS evaluation method was used to evaluate the land ecological security in Xinjiang from 2008 to 2019. The results showed that from 2008 to 2019, the overall level of land ecological security in Xinjiang presented a slow upward trend, the level of land ecological security was gradually improved, and the land security status was upgraded from an unsafe level to a relatively safe level. From the perspective of subsystems, the driving force system of Xinjiang land ecological security changed from unsafe state to relatively safe state, the state system, influence system and response system changed from unsafe state to safe state, and the pressure system showed a downward trend from a safe state to an unsafe state. From 2008 to 2019, the overall level of land ecological security in all prefectures, cities and districts in Xinjiang showed a slow upward trend, and the level of land ecological security gradually improved. There were obvious regional differences in the land ecological security situation, and the land ecological security situation in northern Xinjiang was higher than that in southern Xinjiang on the whole.
