The so-called ecological balance means that in the relatively stable status of an ecosystem in a specific time period, material and energy input equals to their output. Also by self-adjusting, the ecosystem can rehabilita…

| Abstract: | In landscape with overpopulation, intensive management for economic production, and where even small natural-vegetation patches
are scarce, ecological conservation generally must be developed in the course of economic development. Thus “landscape ecological
construction” has evolved in China. This approach adds spatial elements and alters landscape pattern to strengthen inter-ecosystem
linkages, improve functioning of damaged ecosystems, and increase productivity and stability of the whole landscape. Five
examples of managed landscapes in China are presented: dike-pond systems in a river delta; multi-pond system in a rice paddy
landscape; field-grass-wood grid system on unstable sand dunes; shelterbelt network in a crop field area; and field-grass-wood
mosaic system on highly erodible hilly farmland. These indicate that ecological conditions can be improved along with increased
economic production. Altering landscape structure and ecological flows by introducing small landscape elements in distinct
spatial patterns is considered a key to the results. This reshaping of the land has focused on changing patch size, regularity
of arrangement, biological and hydrological corridors, and networks, the matrix and grain size. It suggests that such changes
can increase negative feedbacks and increase stability. Finally, planning and design principles are pinpointed for the landscape
ecological construction process.
