agricultural reclamation
1.Forty or fifty years ago, while the agricultural reclamation soldiers of the Corps and their family staff came to Xinjiang, wasteland and weeds were everywhere.
2.A policy of linking the appropriation of land for non-agricultural construction purposes to land development and reclamation will be implemented.
3.Agricultural land use plan shall be updated to readjust crop production structure, actively develop green agriculture, return the related farmland to forest and grassland and stop new reclamation for agricultural use.
4.The purpose of this web site is to share my experiences with workers in any country on water logging in agricultural lands, irrigation induced soil salinity, subsurface drainage for agriculture (horizontal and vertical), reuse of groundwater, ground-water hydraulics, (geo)hydrology, rainfall and surface runoff relations, reclamation and improvement of water logged saline, salty, sodic alkaline, and acid sulphate soils, plant growth, crop production and responses as well as statistical analysis consisting of segmented linear regression and cumulative frequency distributions.
5.Wastewater reclamation facilities will be developed along with the set-up of sewerage treatment plants. By 2005, the wastewater reclamation after necessary treatment in urban area will reach 300 million cubic meters (reuse for agricultural and industrial purposes, municipal use, green land irrigation and supplementary of waterways). The reuse rate of effluent from the sewerage treatment plants will go up to about 50% by 2008.
6.Also known as the China Xinjian Group, the XPCC has 14 divisions (reclamation areas), 174 regimental agricultural and stockbreeding farms, 4,391 industrial, construction, transport and commercial enterprises, and well-run social undertakings covering scientific research, education, culture, health, sports, finance and insurance, as well as judiciary organs. The total population of the XPCC is 2,453,600, including 933,000 workers.
7.Abstract: This paper analyzes causal factors of flood in the middle reaches of Changjiang River.Due to neglection of environmental management,soil erosion in the upper and middle reaches of the Changjiag River,lake sedimentation,large-scale reclamation of marshes,the flood regulation capacity of the lake was descended,and flood stage was risen and prolonged.Consequently more and more river levees and lake dikes were reinforced almost every year to prevent the disasters,which made flood level go up and flood period last for more days.The frequency of flood and waterlogging disasters rose and their damage was enlarged.Several proposals for flood prevention including agricultural modernization are put forward.
