采用的Fragstats313景观计算软件,可以相应计算景观3个级别上(斑块、类型、景观)的大约4O多个指标。例如以研究景观结构为主,所选指数主要是为反映景观最基本结构信息,具体选用了斑块个数(NP)、景观类型面积(CA)、景观类型百分比(%LAND)、拼块平均大小(MPS)、最大斑块面积百分比( largest patch index,LPI)、景观类型斑块破碎度指数(perimeter area fractal dimension )、景观优势度指数( landscape dominanc

3DEC是3 Dimension Distinct Element Code的缩写，即三维离散单元法程序，顾名思义，3DEC是一款基于离散单元法作为基本理论以描述离散介质力学行为的计算分析程序。概括来讲，3DEC程序承袭了UDEC的基本核心思想，本质上是对二维空间离散介质力学描述向三维空间延伸的结果。目前中国区域（包括香港，澳门）3DEC软件销售工作都由ITASCA中国公司负责。

NetCDF全称为network Common Data Format，一个netcdf文件的结构包括以下对象：
1、变量(Variables)
变量对应着真实的物理数据。比如说温度。
2、维(dimension)
一个维对应着函数中的某个自变量，或者说函数图象中的一个坐标轴，在线性代数中就是一个N维向量的一个分量（这也是维这个名称的由来）。在netcdf中，一个维具有一个名字和范围（或者说长度，也就是数学上所说的定义域，可以是离散的点集合或者连续的区间）
3、属性(Attribute
