Glossary-existing land

I suddenly found that many terms are unknown, as if I sat down on the sixth day and went out ~~~

What does "Inventory of land" mean when I perform online review? It means that a land ownership certificate has been completed in a certain land, but for various reasons, such as lack of development, or the land is occupied by other cattle, and there is no chance to use the land on its own. As a result, the land is either idle, or you have to rent it by yourself or directly transfer it to the cattle.

I hope someone can take the lead, so that we will not be confused all day in the universe.

PS: record a concept example

Land Utilization Rate: an indicator that reflects the degree of land development and utilization. It is usually indicated by the proportion of the used land to the total land area. The main indicators for measuring land utilization rate are: ① utilization rate of agricultural land. The proportion of the land used by a region or agricultural production unit for agricultural production (including agricultural, forest, animal husbandry, secondary, and fishery) to the total land area, it is an indicator to measure the degree of utilization of agricultural land in a region or agricultural production unit; ② non-agricultural land utilization rate. The proportion of non-agricultural land occupied by a region or agricultural production unit (including urban residential areas, industrial and mining, transportation, tourism, military fields, etc.) in the total land area, it is an indicator that reflects the land occupation status of non-agricultural land; ③ reclamation index. It refers to the proportion of the cultivated land area occupied by reclamation to the total land area, which is an indicator to measure the degree of development and utilization of cultivated land in a region or agricultural production unit; ④ resumption index. The indicator indicating the reuse of cultivated land within one year. In the process of land development and utilization, all land resources that can be developed and used must be fully and reasonably developed and used according to local conditions without causing soil erosion or damage to the ecological environment, to improve land utilization.
