[Abstract]:Based on the evaluation of the suitability for cultivated land in unused land and industrial and mining wasteland, the development time series and ecological profit and loss of cultivated land reserve resources in Xiangyang city were discussed. The results showed that the suitable tillage area of Xiangyang city was 30 074.26 hm2, including barren grassland and tidal flat. The sequence of development of cultivated land reserve resources in Xiangyang city, such as sand land and industrial and mining wasteland, is as follows: first to develop 23. 62%) than to develop first, 65.30)) to develop 7. 91%) then to develop 3. 17%). The sequence of development of counties (districts) is Yicheng, Zaoyang, Xiangzhou, Gucheng, Laohekou, etc, and the sequence of each county (district) is Yicheng, Zaoyang, Xiangzhou, Gucheng, Laohekou, etc. The total value of ecological services for cultivated land reserve resources in Nanzhang County, Xiangcheng District, Fancheng District and Baokang County decreased from 642 million yuan to 191 million yuan before and after development, and the value of food production and raw material production increased by 21 million yuan and 1 million yuan respectively.
