What does reclamation mean?

Generally refers to the process of reclaiming unused wasteland and converting it into farmland. Abbreviation for reclaiming wasteland. One of the ways to expand the scale of agricultural production and increase the total output of agricultural products.

Wasteland resources include raw wasteland and mature wasteland. The former refers to land that has never been cultivated, also known as virgin land. The latter is also called abandoned land, which refers to land that has been cultivated for planting, but due to improper land use measures, land productivity has seriously declined, or has been abandoned for more than 3 years due to natural disasters, wars, etc., excluding land that is in rotation to restore soil fertility. Intentional recreational spots during the cycle. A comprehensive survey must be conducted on the land to be reclaimed. China's wasteland suitable for agriculture is divided into four categories: Type I wasteland refers to wasteland that can be cultivated without taking any measures. Class II wasteland refers to wasteland that can be reclaimed with slight improvements. Category III wasteland refers to wasteland that can be reclaimed after improvement. The fourth category of wasteland refers to wasteland that is not suitable for cultivation.

There are two main methods of modern land reclamation in China: ① For large areas of wasteland in remote areas, the state invests in the construction of state-owned agricultural (pastoral) farms for large-scale reclamation, uses state agricultural machinery to reclaim the land, and then immigrate people to cultivate it. Such as Beidahuang Farm in Heilongjiang Province and large farm groups in Xinjiang and coastal areas. ② For small pieces of wasteland in close proximity, collective economic units usually organize the masses to reclaim and utilize it. The reclamation process will inevitably change the original ecological environment. Therefore, reclamation must be combined with protection and the establishment of a new ecological balance, and should be considered uniformly. The main measures include protecting forests, grasslands and water and soil resources; not clearing land on steep slopes; building water and soil conservation projects during reclamation on gentle slopes to prevent water and soil erosion; not easily enclosing lakes and rivers to create farmland, so as to maintain and exert the water regulation and storage functions of rivers and lakes , to prevent flood disasters and protect aquatic resources; when reclaiming land from the sea, prevent it from affecting the water storage and drainage capacity of aquaculture, coastal zone construction and sea undercurrent projects, so as to avoid adverse effects on the surrounding environment; prevent atmospheric, water and soil pollution, etc.
