However, the solutions of the Cauchy problem of the nonlinear hyperbolic system generally develop singularities in finite time even if the initial data are small and smooth.For this reason, solutions must be found in the space of discontinuous functions. Therefore, one can not directly use the classical analytic techniques that predominate in the theory of partial differential equations of other types. Instead, we construct approximate solutions via the singular perturbation methods. By using the compactness of the approximate solutions, we can obtain the existence of the solutions of original system.

然而一般而言，即使是在初值很小且光滑的情况下，非线性双曲型守恒律的Cauchy问题的解在有限时间内也会出现奇异性，为此，我们必须在不连续函数空间中寻找上述问题的解，因此对这类问题的研究，我们也不可能直接利用在其它类型的偏微分方程中占主导地位的解析方法来解决问题，而是通过奇异扰动法构造近似解，由近似解的紧性得到原问题解的存在性。

But this kind of entity may insurmountably have some uncertainties when it is expressed abstractly to the spatial object of GIS, and these uncertainties are the uncertain factors including error, inaccuracy, illegibility and so on.

但是这类实体在抽象描述为GIS的空间目标时难以避免地会带有一定程度的不确定性，这种不确定性指的是在进行抽象描述时随之产生的误差、不精确性、模糊性和含混性等不确定性因素。

In this paper, the Basin of Northwest Hebei Mountains as the study area, the combination of the remote sensing and GIS technologies will be applied, Firstly the objects of evaluation include forest land、. meadow 、 a part of orchard、 uncultured grass land、 sandlot、 bare land and the margin suitable and unsuitable farming land, the unit of evaluation is 30m*30m grid. Secondly, on the base of probling and building the spatial and attributive database of suitability evaluation through models such as digital elevation and inverse distance weighed interpolation, it establishs the factor system of suitability evaluation of forest land.
