简述：普瑞时空数据建库软件（国土变更调查建库）之一(批量变更图斑)
变更建库流程图如上所示：
其中批量变更图斑即PLBGDLTB图层是本软件中的核心图层，在空间库geodb.gdb中，新建此图层。
「PLBGDLTB」用于控制
DLTB（地类图斑）、
CJDCQ（村级调查区）、
XZQ（行政区）和
CZCDYD（城镇村等用地）图层的变更。
对于这些图层的任何变更，都需要通过PLBGDLTB图层来进行控制。
仅需修改本图层的属性和图斑范围，PLBGDLTB图层可以自动修改其他相关图层，
实现一处变更多处自动修改的功能。

PLBGDLTB图层字段结构说明：
注：该图层仅保留了必要的属性字段，已省略相同含义的名称字段。程序在一键生成成果时会自动根据代码字段匹配对应的名称字段内容，例如通过DLBM赋值DLMC，或通过ZZSXDM赋值ZZSXMC，既避免了误操作，也节省了输入时间。
PLBGDLTB图层中GDPDJB、KCXS字段赋值规则：
GDLX字段赋值一般规则：
当GDPDJB为2、3、4、5时，DLBM为0101水田时，GDLX=TT
当GDPDJB为2、3、4、5时，DLBM为0102水浇地或0103旱地时，GDLX=PD
其他情况时，GDLX将自动判断为空值。
对于特殊情况时，则需要手动赋值GDLX字段值。
