Trend of cultivated land use and ways of protective exploitation in Bohai Rim

Based on social and economic statistical data, general surveys, detailed surveys and analysis as well as field surveys and investigations of land in rural areas of the Bohai Rim since the 1980s, firstly, this paper analyses the trend of cultivated land occupation inevitably related to population growth, urbanization, development of industry, development of transportation facilities and water conservancy, construction of environment, and natural disasters in the surroundings of the Bohai Sea. Secondly, it examines the position of cultivated land quantity degradation and quality improvement related to less support of farmland resources, low quality of opened up land, greater exploitation difficulty, and necessity of making intensive use of farmland in the study area. Thirdly,it puts forward measures for farmland protection such as strict management of land use, strict control of farmland occupation for construction purposes, achieving overall balance of farmland quantitatively, protection of basic farmland and cultivated land in key region, transformation of middle low yield farmland, controlling of groundwater exploitation, protection of farmland eco environment, and adjustment of agricultural structure in the surroundings of the Bohai Sea. Fourthly, it discusses land increment potentials and ways of exploitation related to policy of land use management, farmland and village consolidation for sustainable land use, land reclamation and land exploitation in Bohai Rim.
