    Abstract:

    [Objective] Screening of provincial land resources assets auditing divisions and identifying the land-control resource priorities in each city were conducted in order to improve the efficiency of auditing land assets in China, and to mprove the application of geographic information technology for homeland audit.[Methods] Based on the perspective of land landscape pattern, ENVI and ArcGIS were used to convert the four phases of remote sensing image data from 2000, 2005, 2010 and 2015 in Zhejiang Province to the grid resolution of 30 m ArcGrid data format. Also, Fragstats 3.3 was used to calculate the degree of fragmentation and concentration of the land, which is used as the key selection criteria for the audit of land resources in Zhejiang Province.[Results] ① We have constructed an important regional geographic audit model for land resources assets based on the land fragmentation index and the concentration index. It focuses on a global review of the quantity and quality changes of land use types in each jurisdiction, and can reveal the use and protection scenarios of land-based resource assets across the audit area and variation trend. It confirms that the application of landscape ecological assessment to land resources assets leading cadres leaving audit are effective. It also helps to remedy the shortcomings of the past audits of leading cadres, which only simply measures the number of assets and ignore the measure of ecological value; ② Dominant land types were empirically screened out in Zhejiang Province:woodland, grassland, and water areas in Hangzhou City; cultivated land and water areas in Huzhou City; cultivated land and construction land in Jiaxing City; cultivated land, grassland, construction land in Jinhua City; forest land in Lishui City; water areas in Ningbo City; forest land and grassland in Cangzhou City; cultivated land and construction land in Shaoxing City; grassland in Taizhou City; grassland in Wenzhou City; construction land in Zhoushan City. The audits of the quantity and quality of land types mentioned in various cities of Zhejiang Province should be the focus of the audit of the departure of leading cadres of land resources assets.[Conclusion] When auditing land resources assets, we should pay attention to the combination of land resource inventory and modern geographic information technology to enhance the visual interpretation of the recognition efficiency and audit results of regional subjects.
