The limited amount of cultivated land reserve resources in the country is reduced by 74%.
[ China Agricultural Machinery Industry News ] The Ministry of Land and Resources held a press conference on the results of the survey on the reserve resources of cultivated land on December 28th. Feng Wenli, deputy director of the Department of Cadastral Management of the Ministry, said at the meeting that the results of this round of surveys show that The reserve resources of cultivated land totaled 28.302 million mu, which was reduced by 81.837 million mu compared with the same round of the previous round, with a decrease of 74%.
This shows that after years of land use and remediation and development, most of the cultivated land reserve resources that have been scaled up and easily developed have been developed and utilized. The existing cultivated land reserve resources are mainly broken and scattered, and the development and utilization of cultivated land reserve resources also needs to be shifted from centralized development to comprehensive improvement as the main approach.
The summary results show that the total area of ​​cultivated land reserve resources in the country is 80,219,500 mu. Among them, the land can be reclaimed 77.426 million mu, accounting for 96.4%, and the land reclamation can be 2.865 million mu, accounting for 3.6%. The country's cultivated land reserve resources are mainly for reclamation of grassland (516.162 million mu), openable saline-alkali land (976.49 million mu), open inland tidal flat (701.31 million mu) and openable bare land (641.60 million mu), accounting for arable land reserve. 93.2% of the total resources.
Combined with the current conditions of water use restrictions and other conditions, the country can develop and use 3,307,800 mu of cultivated land reserve resources in the near future. Among them, the concentration of contiguous arable land reserve resources is 9.4426 million mu, and the scattered reserve resources of arable land are 23.6692 million mu. The remaining reserves of 47.219 million mu of cultivated land are restricted by water resources utilization and are not suitable for development and utilization in the short term.
Feng Wenli said that the current total area of ​​cultivated land reserve resources in the country is 80,219,500 mu, which is nearly 30 million mu compared with the previous round. The total amount is not much different, but the internal composition of cultivated land reserve resources has changed significantly. On the one hand, in the evaluation results of this round of surveys, the reserve resources of contiguous arable land were 28.32 million mu, which was reduced by 81.837 million mu compared with the previous round, with a reduction of 74%. This shows that after years of land use and remediation and development, most of the cultivated land reserve resources that have been scaled up and easily developed have been developed and utilized. On the other hand, the current round of investigation and evaluation is based on the second survey, according to the survey of 2 acres of small map area, the survey method is more comprehensive, the scope of the survey is more comprehensive, and all the reserve resources of scattered cultivated land that were not investigated in the previous round were all investigated. This part of the cultivated land reserve resources area is 5,197.0 million mu. That is to say, the existing cultivated land reserve resources are mainly broken and scattered, and the development and utilization of cultivated land reserve resources also needs to be shifted from centralized development to comprehensive improvement as the main approach.
According to the results of the survey and evaluation, except for the three provinces of Heilongjiang, Henan and Guizhou, the same calibers have been increased compared with the previous round, and the other 28 provinces are decreasing. The 10 provinces including Beijing, Tianjin, Jiangsu and Fujian have decreased more than 90%. This reflects that with the development of land for many years, most of the large-scale continuation of arable land has been developed into cultivated land, garden land, forest land and so on. According to the statistics of land change surveys, between 2002 and 2014, the country's unused land was developed into 31.77 million mu of cultivated land, developed into 3.17 million mu of garden land, and developed into 25.06 million mu of forest land. This also shows that most of the backup resources that were easy to develop in the early stage have been developed, and the work foundation for continuing to implement large-scale land development and utilization is no longer available.
Feng Wenli said that the amount of cultivated land reserve resources currently available for development and utilization is limited. The comprehensive analysis shows that the area of ​​cultivated land reserve resources available for development and utilization in the near future is 3,307,800 mu, accounting for 41.1% of the total reserve resources of cultivated land. Among them, the reserve resources of concentrated contiguous arable land is only 9.4426 million mu, and the distribution is extremely uneven. The sum of the two provinces and regions of Xinjiang (2,682,100 mu) and Heilongjiang (1,700,100 mu) accounts for 49.5 of the total reserve resources of concentrated contiguous arable land. %, while the sum of the 11 provinces (cities) in the east only accounts for 11.7%, and each province (city) has an average of less than 100,000 mu. The scattered reserve of cultivated land is 23.6692 million mu, and the distribution is relatively even. There are more Hunan (311.77 million mu), Heilongjiang (304.20 million mu), Guizhou (2,238,100 mu) and Henan (2,203,600 mu).
In view of the grim situation in which the amount of cultivated land reserve resources currently available for development and utilization is limited, Feng Wenli said that the land and resources department will continue to adhere to strict farmland protection systems, strengthen land use control for cultivated land occupation, strengthen special protection of basic farmland, and firmly hold 1.8 billion mu. Cultivated land red line. At the same time, the Ministry of Land and Resources will reasonably determine the development and utilization timing of cultivated land reserve resources, improve the development and utilization efficiency of cultivated land reserve resources, and implement the “three-in-one†protection of the quantity, quality and ecology of cultivated land.
