Melioracijos statinių būklės analizė Vilniaus rajone ; Analysis of the State of Reclamations Construction in the Vilnius Region
The condition of reclaimed lands and of land reclamation hydraulic structures was analyzed in the final work of master studies. Research was carried out in the district of Vilnius. 43224,8 ha or 67,8% of the wetlands fund (56269 ha) have been reclaimed in the district. In the period of 1960-2008, 39061,4 ha were reclaimed and in the period of 1976-1980, 1800 ha per year were reclaimed. The smallest areas returned for the use were in 1996-2000, 155,7 ha per year and the largest areas returned for the use were in 1985, 1400 ha were reclaimed. From 2000, no new construction was carried out. With the help of the research of reclaimed lands and the condition of land reclamation hydraulic structures in Vilnius district, it was determined that the technical condition of land reclamation structures and reclaimed lands which was in good condition is now deteriorating every year. The grant committed to the land reclamation works, issued by the Ministry of Agriculture, is not sufficient for ensuring that these structures remain in good condition. In order to maintain the good condition of reclaimed lands and land reclamation hydraulic structures situated in Vilnius district, the State should commit 4 million Lt during the year, i.e. a fourfold increase. At present, the average age of land reclamation hydraulic structures is 35 years old. Farmers do not have enough funds for the proper use and exploitation of land reclamation hydraulic structures, therefore, their condition is rapidly deteriorating. Land reclamation structures are useful to farmers, rural inhabitants as well as to the entire society. The farmers, unwilling and unable to maintain and exploit drainage on their own lands, do significant harm to their neighbor’s drained lands. The land reclamation hydraulic structures should not disappear, because their reconstruction would cost a great deal of money. Therefore, they should be properly exploited and maintained in order to prolong their exploitation time. The data of mathematical statistics methods, such as data system, grouping as well as the methods of the graphical expression of research data were used for the research.
