Summary: Assume that \(\mathbb{K}\) is Gaussian field, and \(a_{\mathbb{K}}(n)\) is the number of non-zero integral ideals in \(\mathbb{Z}[i]\) with norm \(n\). We establish an Erdős-Kac type theorem weighted by \(a_{\mathbb{K}}(n^2)^l\; (l\in\mathbb{Z}^+)\) in short intervals. We also establish an asymptotic formula for the average behavior of \(a_{\mathbb{K}}(n^2)^l\) in short intervals.
