摘要:

Although the early efforts to save San Francisco Bay in the 1960's provided the role model for protection of California's 1100 mile ocean coastline, neither Proposition 20 of 1972 nor the California Coastal Act of 1976 provided any benefits to San Francisco Bay. One result is that the Bay is locked into its urban, shoreline‐use dominated plan of 1969 while every other estuary and coastal wetland in California receives much stronger protection of its resources. Furthermore, due to the complexity of California's water laws, there is no instream flow protection for receiving waters such as San Francisco Bay. This is particularly critical considering that 70% of the Bay's freshwater inflow has been diverted. The Bay's present decline as the largest and most important estuary on the West Coast, as well as its possible death as an estuary, may be irreversible. The problem requires the immediate attention of engineering, scientific, economic and legal disciplines if San Francisco Bay is to be saved.

摘要:

To be useful for decision making, coastal zone information systems must have the following attributes: 1) they must store indexed and referenced data about the coastal zone; 2) they must be able to select spatially relevant data; 3) they must be able to transform the data into output parameters pertinent to the decision; 4) they must translate the output into a form that is readily understood by the group or individual that will make the decision.

摘要:

Acreages and vegetative cover types of areas identified as former rice fields were determined from topographic maps and aerial photographs with verification by ground checks. Sixteen vegetative cover types were recognized and 74, 113 acres of former rice fields were located. Each drainage system studied had roughly the same acreage, but different proportions of cover types.
