Facing the severity of flood and waterlogging disasters and ecological vulnerability, the key techniques and exploitation models for wetland farming are emphatically discussed. These key techniques include: planning and its implement for the comprehensive reclamation and development model zone construction in the waterlogged area;
The main tasks and objectives of the comprehensive harnessment and development are: to stabilize the river channel, to develop and utilize fresh water resources reasonably, to protect the ecological environment, to improve the navigation channel condition, to reclaim beach resources with combination of navigation channel improvement and to control flood and tide.

A set of systematic evaluation indexes is established for evaluating effects of infrastructure construction and comprehensive development in two demonstration zones in waterlogged lands in South China. The evaluation system consists of three parts: effects of infrastructure construction, effects of comprehensive development in agriculture, and effects in integrated benefits. The effects of infrastructure construction is evaluated with reduction of flooding disaster loss, waterlogging and drought disasters l...
