Based on the data of land use status in 2009-2018 in the annual change survey results of Pu er City,Yunnan Province,China,the habitat quality in the city were studied by using InVEST models.The results show that the area of cultivated land,construction land,and unused land in Pu er City continuously increased from 2009 to 2018.The growth rate of cultivated land and construction land in the next three years was significantly higher than that in the previous three years,while the area of gardens,grassland and woodland continuously decreased.From 2009 to 2018,the habitat quality in Pu er City showed a downward trend,that is,there was a clear increase in the proportion of moderate and poor habitat quality and a decrease in the proportion of superior and good habitat quality.Changes in habitat quality calculated by InVEST models can be used as a grasp of regional ecological environment in the investigation before the audit of natural resource assets and breakthroughs in finding clues of problems,thereby improving the scientificity and efficiency of audit work of natural resource assets. 展开更多
