Further Considerations
There are some notable considerations to the application of
this research.First,the GIS-based statewide LDI map of
Florida was constructed based on the available 1995 land
use maps,which were approximately 5–8 years old when
site visits were completed (1999–2002).There is no doubt
the rapid urbanization of Florida’s coastline far outpaces
the available GIS land use maps.However,as a landscape
level tool,perhaps the best available land use maps are
sufficient to characterize ecosystem condition in the
broadest sense,and improving accuracy of land use maps
can only strengthen our predictive capabilities.
A second consideration includes the accuracy of available
land use maps for Level 1 assessment methods.For
example,in areas designated as ‘‘Natural Lands,’’ there may
be instances when the polygon should receive a higher LDI
index score.For example,perhaps the land had historically
been used for native pasture or had been recently managed
as restoration lands.In these cases,the predicted level of
ecosystem condition may be considerably higher than expected
based on a Level 1 LDI index assessment.Another example is the designation of ‘‘Natural Lands’’ for most of
the Florida Everglades,which is unquestionably a highly
engineered system with altered hydrologic and nutrient
regimes (Belanger et al.,1989; Redfield et al.,2000).As such,
the inferred ecosystem condition in the Florida Everglades
may be higher than the actual condition found in the field.
When discrepancies are detected between the available land
use maps and the current land use,more rigorous Levels 2
and 3 assessment procedures should be employed.
进一步审议
有一些值得注意的因素的应用
这项研究.首先,地理信息系统为基础的LDI州地图
佛罗里达州的基础上构建了1995年的可用土地
使用的地图,其中约5-8岁时,
实地考察已完成( 1999-2002年) .毫无疑问
在快速城市化的佛罗里达州的海岸线远远超过
现有的地理信息系统的土地利用图.但是,作为一个景观
水平的工具,也许是最好的土地利用图
充足的条件下生态系统的特点在
广义上讲,并改进了精确性的土地利用图
只能加强我们的预测能力.
第二个考虑,包括现有的准确性
土地利用图的第1级评估方法.为了
例如,在地区指定为''自然土地,''可能
被实例多边形时应该获得较高的LDI
指数评分.举例来说,或许是土地在历史上
用于本地牧场或最近已管理
恢复土地.在这种情况下,预测水平
生态系统的状况可能大大高于预期
基于1级的LDI指数评估.另一个例子是指定地政'' ''天然的大部分
佛罗里达大沼泽地,这无疑是一个高度
工程水文系统的改变和养分
制度(贝朗格等.,1989年;莱德菲尔德等.,2000年) .因此,
推断生态条件在佛罗里达大沼泽地
可能高于实际情况,发现在该领域.
当被检测的差异之间的可用土地
使用地图和目前的土地使用,更严格的等级2
3评估程序应采用.
